+Commit Limiting
+~~~~~~~~~~~~~~~
+
+Besides specifying a range of commits that should be listed using the
+special notations explained in the description, additional commit
+limiting may be applied.
+
+Using more options generally further limits the output (e.g.
+`--since=<date1>` limits to commits newer than `<date1>`, and using it
+with `--grep=<pattern>` further limits to commits whose log message
+has a line that matches `<pattern>`), unless otherwise noted.
+
+Note that these are applied before commit
+ordering and formatting options, such as `--reverse`.
+
+-<number>::
+-n <number>::
+--max-count=<number>::
+	Limit the number of commits to output.
+
+--skip=<number>::
+	Skip 'number' commits before starting to show the commit output.
+
+--since=<date>::
+--after=<date>::
+	Show commits more recent than a specific date.
+
+--until=<date>::
+--before=<date>::
+	Show commits older than a specific date.
+
+ifdef::git-rev-list[]
+--max-age=<timestamp>::
+--min-age=<timestamp>::
+	Limit the commits output to specified time range.
+endif::git-rev-list[]
+
+--author=<pattern>::
+--committer=<pattern>::
+	Limit the commits output to ones with author/committer
+	header lines that match the specified pattern (regular
+	expression).  With more than one `--author=<pattern>`,
+	commits whose author matches any of the given patterns are
+	chosen (similarly for multiple `--committer=<pattern>`).
+
+--grep-reflog=<pattern>::
+	Limit the commits output to ones with reflog entries that
+	match the specified pattern (regular expression). With
+	more than one `--grep-reflog`, commits whose reflog message
+	matches any of the given patterns are chosen.  It is an
+	error to use this option unless `--walk-reflogs` is in use.
+
+--grep=<pattern>::
+	Limit the commits output to ones with log message that
+	matches the specified pattern (regular expression).  With
+	more than one `--grep=<pattern>`, commits whose message
+	matches any of the given patterns are chosen (but see
+	`--all-match`).
+ifndef::git-rev-list[]
++
+When `--show-notes` is in effect, the message from the notes is
+matched as if it were part of the log message.
+endif::git-rev-list[]
+
+--all-match::
+	Limit the commits output to ones that match all given `--grep`,
+	instead of ones that match at least one.
+
+--invert-grep::
+	Limit the commits output to ones with log message that do not
+	match the pattern specified with `--grep=<pattern>`.
+
+-i::
+--regexp-ignore-case::
+	Match the regular expression limiting patterns without regard to letter
+	case.
+
+--basic-regexp::
+	Consider the limiting patterns to be basic regular expressions;
+	this is the default.
+
+-E::
+--extended-regexp::
+	Consider the limiting patterns to be extended regular expressions
+	instead of the default basic regular expressions.
+
+-F::
+--fixed-strings::
+	Consider the limiting patterns to be fixed strings (don't interpret
+	pattern as a regular expression).
+
+-P::
+--perl-regexp::
+	Consider the limiting patterns to be Perl-compatible regular
+	expressions.
++
+Support for these types of regular expressions is an optional
+compile-time dependency. If Git wasn't compiled with support for them
+providing this option will cause it to die.
+
+--remove-empty::
+	Stop when a given path disappears from the tree.
+
+--merges::
+	Print only merge commits. This is exactly the same as `--min-parents=2`.
+
+--no-merges::
+	Do not print commits with more than one parent. This is
+	exactly the same as `--max-parents=1`.
+
+--min-parents=<number>::
+--max-parents=<number>::
+--no-min-parents::
+--no-max-parents::
+	Show only commits which have at least (or at most) that many parent
+	commits. In particular, `--max-parents=1` is the same as `--no-merges`,
+	`--min-parents=2` is the same as `--merges`.  `--max-parents=0`
+	gives all root commits and `--min-parents=3` all octopus merges.
++
+`--no-min-parents` and `--no-max-parents` reset these limits (to no limit)
+again.  Equivalent forms are `--min-parents=0` (any commit has 0 or more
+parents) and `--max-parents=-1` (negative numbers denote no upper limit).
+
+--first-parent::
+	Follow only the first parent commit upon seeing a merge
+	commit.  This option can give a better overview when
+	viewing the evolution of a particular topic branch,
+	because merges into a topic branch tend to be only about
+	adjusting to updated upstream from time to time, and
+	this option allows you to ignore the individual commits
+	brought in to your history by such a merge. Cannot be
+	combined with --bisect.
+
+--not::
+	Reverses the meaning of the '{caret}' prefix (or lack thereof)
+	for all following revision specifiers, up to the next `--not`.
+
+--all::
+	Pretend as if all the refs in `refs/`, along with `HEAD`, are
+	listed on the command line as '<commit>'.
+
+--branches[=<pattern>]::
+	Pretend as if all the refs in `refs/heads` are listed
+	on the command line as '<commit>'. If '<pattern>' is given, limit
+	branches to ones matching given shell glob. If pattern lacks '?',
+	'{asterisk}', or '[', '/{asterisk}' at the end is implied.
+
+--tags[=<pattern>]::
+	Pretend as if all the refs in `refs/tags` are listed
+	on the command line as '<commit>'. If '<pattern>' is given, limit
+	tags to ones matching given shell glob. If pattern lacks '?', '{asterisk}',
+	or '[', '/{asterisk}' at the end is implied.
+
+--remotes[=<pattern>]::
+	Pretend as if all the refs in `refs/remotes` are listed
+	on the command line as '<commit>'. If '<pattern>' is given, limit
+	remote-tracking branches to ones matching given shell glob.
+	If pattern lacks '?', '{asterisk}', or '[', '/{asterisk}' at the end is implied.
+
+--glob=<glob-pattern>::
+	Pretend as if all the refs matching shell glob '<glob-pattern>'
+	are listed on the command line as '<commit>'. Leading 'refs/',
+	is automatically prepended if missing. If pattern lacks '?', '{asterisk}',
+	or '[', '/{asterisk}' at the end is implied.
+
+--exclude=<glob-pattern>::
+
+	Do not include refs matching '<glob-pattern>' that the next `--all`,
+	`--branches`, `--tags`, `--remotes`, or `--glob` would otherwise
+	consider. Repetitions of this option accumulate exclusion patterns
+	up to the next `--all`, `--branches`, `--tags`, `--remotes`, or
+	`--glob` option (other options or arguments do not clear
+	accumulated patterns).
++
+The patterns given should not begin with `refs/heads`, `refs/tags`, or
+`refs/remotes` when applied to `--branches`, `--tags`, or `--remotes`,
+respectively, and they must begin with `refs/` when applied to `--glob`
+or `--all`. If a trailing '/{asterisk}' is intended, it must be given
+explicitly.
+
+--reflog::
+	Pretend as if all objects mentioned by reflogs are listed on the
+	command line as `<commit>`.
+
+--alternate-refs::
+	Pretend as if all objects mentioned as ref tips of alternate
+	repositories were listed on the command line. An alternate
+	repository is any repository whose object directory is specified
+	in `objects/info/alternates`.  The set of included objects may
+	be modified by `core.alternateRefsCommand`, etc. See
+	linkgit:git-config[1].
+
+--single-worktree::
+	By default, all working trees will be examined by the
+	following options when there are more than one (see
+	linkgit:git-worktree[1]): `--all`, `--reflog` and
+	`--indexed-objects`.
+	This option forces them to examine the current working tree
+	only.
+
+--ignore-missing::
+	Upon seeing an invalid object name in the input, pretend as if
+	the bad input was not given.
+
+ifndef::git-rev-list[]
+--bisect::
+	Pretend as if the bad bisection ref `refs/bisect/bad`
+	was listed and as if it was followed by `--not` and the good
+	bisection refs `refs/bisect/good-*` on the command
+	line. Cannot be combined with --first-parent.
+endif::git-rev-list[]
+
+--stdin::
+	In addition to the '<commit>' listed on the command
+	line, read them from the standard input. If a `--` separator is
+	seen, stop reading commits and start reading paths to limit the
+	result.
+
+ifdef::git-rev-list[]
+--quiet::
+	Don't print anything to standard output.  This form
+	is primarily meant to allow the caller to
+	test the exit status to see if a range of objects is fully
+	connected (or not).  It is faster than redirecting stdout
+	to `/dev/null` as the output does not have to be formatted.
+endif::git-rev-list[]
+
+--cherry-mark::
+	Like `--cherry-pick` (see below) but mark equivalent commits
+	with `=` rather than omitting them, and inequivalent ones with `+`.
+
+--cherry-pick::
+	Omit any commit that introduces the same change as
+	another commit on the ``other side'' when the set of
+	commits are limited with symmetric difference.
++
+For example, if you have two branches, `A` and `B`, a usual way
+to list all commits on only one side of them is with
+`--left-right` (see the example below in the description of
+the `--left-right` option). However, it shows the commits that were
+cherry-picked from the other branch (for example, ``3rd on b'' may be
+cherry-picked from branch A). With this option, such pairs of commits are
+excluded from the output.
+
+--left-only::
+--right-only::
+	List only commits on the respective side of a symmetric difference,
+	i.e. only those which would be marked `<` resp. `>` by
+	`--left-right`.
++
+For example, `--cherry-pick --right-only A...B` omits those
+commits from `B` which are in `A` or are patch-equivalent to a commit in
+`A`. In other words, this lists the `+` commits from `git cherry A B`.
+More precisely, `--cherry-pick --right-only --no-merges` gives the exact
+list.
+
+--cherry::
+	A synonym for `--right-only --cherry-mark --no-merges`; useful to
+	limit the output to the commits on our side and mark those that
+	have been applied to the other side of a forked history with
+	`git log --cherry upstream...mybranch`, similar to
+	`git cherry upstream mybranch`.
+
+-g::
+--walk-reflogs::
+	Instead of walking the commit ancestry chain, walk
+	reflog entries from the most recent one to older ones.
+	When this option is used you cannot specify commits to
+	exclude (that is, '{caret}commit', 'commit1..commit2',
+	and 'commit1\...commit2' notations cannot be used).
++
+With `--pretty` format other than `oneline` (for obvious reasons),
+this causes the output to have two extra lines of information
+taken from the reflog.  The reflog designator in the output may be shown
+as `ref@{Nth}` (where `Nth` is the reverse-chronological index in the
+reflog) or as `ref@{timestamp}` (with the timestamp for that entry),
+depending on a few rules:
++
+--
+1. If the starting point is specified as `ref@{Nth}`, show the index
+   format.
++
+2. If the starting point was specified as `ref@{now}`, show the
+   timestamp format.
++
+3. If neither was used, but `--date` was given on the command line, show
+   the timestamp in the format requested by `--date`.
++
+4. Otherwise, show the index format.
+--
++
+Under `--pretty=oneline`, the commit message is
+prefixed with this information on the same line.
+This option cannot be combined with `--reverse`.
+See also linkgit:git-reflog[1].
+
+--merge::
+	After a failed merge, show refs that touch files having a
+	conflict and don't exist on all heads to merge.
+
+--boundary::
+	Output excluded boundary commits. Boundary commits are
+	prefixed with `-`.
+
+ifdef::git-rev-list[]
+--use-bitmap-index::
+
+	Try to speed up the traversal using the pack bitmap index (if
+	one is available). Note that when traversing with `--objects`,
+	trees and blobs will not have their associated path printed.
+
+--progress=<header>::
+	Show progress reports on stderr as objects are considered. The
+	`<header>` text will be printed with each progress update.

+
+History Simplification
+~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes you are only interested in parts of the history, for example the
+commits modifying a particular <path>. But there are two parts of
+'History Simplification', one part is selecting the commits and the other
+is how to do it, as there are various strategies to simplify the history.
+
+The following options select the commits to be shown:
+
+<paths>::
+	Commits modifying the given <paths> are selected.
+
+--simplify-by-decoration::
+	Commits that are referred by some branch or tag are selected.
+
+Note that extra commits can be shown to give a meaningful history.
+
+The following options affect the way the simplification is performed:
+
+Default mode::
+	Simplifies the history to the simplest history explaining the
+	final state of the tree. Simplest because it prunes some side
+	branches if the end result is the same (i.e. merging branches
+	with the same content)
+
+--full-history::
+	Same as the default mode, but does not prune some history.
+
+--dense::
+	Only the selected commits are shown, plus some to have a
+	meaningful history.
+
+--sparse::
+	All commits in the simplified history are shown.
+
+--simplify-merges::
+	Additional option to `--full-history` to remove some needless
+	merges from the resulting history, as there are no selected
+	commits contributing to this merge.
+
+--ancestry-path::
+	When given a range of commits to display (e.g. 'commit1..commit2'
+	or 'commit2 {caret}commit1'), only display commits that exist
+	directly on the ancestry chain between the 'commit1' and
+	'commit2', i.e. commits that are both descendants of 'commit1',
+	and ancestors of 'commit2'.
+
+A more detailed explanation follows.
+
+Suppose you specified `foo` as the <paths>.  We shall call commits
+that modify `foo` !TREESAME, and the rest TREESAME.  (In a diff
+filtered for `foo`, they look different and equal, respectively.)
+
+In the following, we will always refer to the same example history to
+illustrate the differences between simplification settings.  We assume
+that you are filtering for a file `foo` in this commit graph:
+-----------------------------------------------------------------------
+	  .-A---M---N---O---P---Q
+	 /     /   /   /   /   /
+	I     B   C   D   E   Y
+	 \   /   /   /   /   /
+	  `-------------'   X
+-----------------------------------------------------------------------
+The horizontal line of history A---Q is taken to be the first parent of
+each merge.  The commits are:
+
+* `I` is the initial commit, in which `foo` exists with contents
+  ``asdf'', and a file `quux` exists with contents ``quux''. Initial
+  commits are compared to an empty tree, so `I` is !TREESAME.
+
+* In `A`, `foo` contains just ``foo''.
+
+* `B` contains the same change as `A`.  Its merge `M` is trivial and
+  hence TREESAME to all parents.
+
+* `C` does not change `foo`, but its merge `N` changes it to ``foobar'',
+  so it is not TREESAME to any parent.
+
+* `D` sets `foo` to ``baz''. Its merge `O` combines the strings from
+  `N` and `D` to ``foobarbaz''; i.e., it is not TREESAME to any parent.
+
+* `E` changes `quux` to ``xyzzy'', and its merge `P` combines the
+  strings to ``quux xyzzy''. `P` is TREESAME to `O`, but not to `E`.
+
+* `X` is an independent root commit that added a new file `side`, and `Y`
+  modified it. `Y` is TREESAME to `X`. Its merge `Q` added `side` to `P`, and
+  `Q` is TREESAME to `P`, but not to `Y`.
+
+`rev-list` walks backwards through history, including or excluding
+commits based on whether `--full-history` and/or parent rewriting
+(via `--parents` or `--children`) are used. The following settings
+are available.
+
+Default mode::
+	Commits are included if they are not TREESAME to any parent
+	(though this can be changed, see `--sparse` below).  If the
+	commit was a merge, and it was TREESAME to one parent, follow
+	only that parent.  (Even if there are several TREESAME
+	parents, follow only one of them.)  Otherwise, follow all
+	parents.
++
+This results in:
++
+-----------------------------------------------------------------------
+	  .-A---N---O
+	 /     /   /
+	I---------D
+-----------------------------------------------------------------------
++
+Note how the rule to only follow the TREESAME parent, if one is
+available, removed `B` from consideration entirely.  `C` was
+considered via `N`, but is TREESAME.  Root commits are compared to an
+empty tree, so `I` is !TREESAME.
++
+Parent/child relations are only visible with `--parents`, but that does
+not affect the commits selected in default mode, so we have shown the
+parent lines.
+
+--full-history without parent rewriting::
+	This mode differs from the default in one point: always follow
+	all parents of a merge, even if it is TREESAME to one of them.
+	Even if more than one side of the merge has commits that are
+	included, this does not imply that the merge itself is!  In
+	the example, we get
++
+-----------------------------------------------------------------------
+	I  A  B  N  D  O  P  Q
+-----------------------------------------------------------------------
++
+`M` was excluded because it is TREESAME to both parents.  `E`,
+`C` and `B` were all walked, but only `B` was !TREESAME, so the others
+do not appear.
++
+Note that without parent rewriting, it is not really possible to talk
+about the parent/child relationships between the commits, so we show
+them disconnected.
+
+--full-history with parent rewriting::
+	Ordinary commits are only included if they are !TREESAME
+	(though this can be changed, see `--sparse` below).
++
+Merges are always included.  However, their parent list is rewritten:
+Along each parent, prune away commits that are not included
+themselves.  This results in
++
+-----------------------------------------------------------------------
+	  .-A---M---N---O---P---Q
+	 /     /   /   /   /
+	I     B   /   D   /
+	 \   /   /   /   /
+	  `-------------'
+-----------------------------------------------------------------------
++
+Compare to `--full-history` without rewriting above.  Note that `E`
+was pruned away because it is TREESAME, but the parent list of P was
+rewritten to contain `E`'s parent `I`.  The same happened for `C` and
+`N`, and `X`, `Y` and `Q`.
+
+In addition to the above settings, you can change whether TREESAME
+affects inclusion:
+
+--dense::
+	Commits that are walked are included if they are not TREESAME
+	to any parent.
+
+--sparse::
+	All commits that are walked are included.
++
+Note that without `--full-history`, this still simplifies merges: if
+one of the parents is TREESAME, we follow only that one, so the other
+sides of the merge are never walked.
+
+--simplify-merges::
+	First, build a history graph in the same way that
+	`--full-history` with parent rewriting does (see above).
++
+Then simplify each commit `C` to its replacement `C'` in the final
+history according to the following rules:
++
+--
+* Set `C'` to `C`.
++
+* Replace each parent `P` of `C'` with its simplification `P'`.  In
+  the process, drop parents that are ancestors of other parents or that are
+  root commits TREESAME to an empty tree, and remove duplicates, but take care
+  to never drop all parents that we are TREESAME to.
++
+* If after this parent rewriting, `C'` is a root or merge commit (has
+  zero or >1 parents), a boundary commit, or !TREESAME, it remains.
+  Otherwise, it is replaced with its only parent.
+--
++
+The effect of this is best shown by way of comparing to
+`--full-history` with parent rewriting.  The example turns into:
++
+-----------------------------------------------------------------------
+	  .-A---M---N---O
+	 /     /       /
+	I     B       D
+	 \   /       /
+	  `---------'
+-----------------------------------------------------------------------
++
+Note the major differences in `N`, `P`, and `Q` over `--full-history`:
++
+--
+* `N`'s parent list had `I` removed, because it is an ancestor of the
+  other parent `M`.  Still, `N` remained because it is !TREESAME.
++
+* `P`'s parent list similarly had `I` removed.  `P` was then
+  removed completely, because it had one parent and is TREESAME.
++
+* `Q`'s parent list had `Y` simplified to `X`. `X` was then removed, because it
+  was a TREESAME root. `Q` was then removed completely, because it had one
+  parent and is TREESAME.
+--
+
+Finally, there is a fifth simplification mode available:
+
+--ancestry-path::
+	Limit the displayed commits to those directly on the ancestry
+	chain between the ``from'' and ``to'' commits in the given commit
+	range. I.e. only display commits that are ancestor of the ``to''
+	commit and descendants of the ``from'' commit.
++
+As an example use case, consider the following commit history:
++
+-----------------------------------------------------------------------
+	    D---E-------F
+	   /     \       \
+	  B---C---G---H---I---J
+	 /                     \
+	A-------K---------------L--M
+-----------------------------------------------------------------------
++
+A regular 'D..M' computes the set of commits that are ancestors of `M`,
+but excludes the ones that are ancestors of `D`. This is useful to see
+what happened to the history leading to `M` since `D`, in the sense
+that ``what does `M` have that did not exist in `D`''. The result in this
+example would be all the commits, except `A` and `B` (and `D` itself,
+of course).
++
+When we want to find out what commits in `M` are contaminated with the
+bug introduced by `D` and need fixing, however, we might want to view
+only the subset of 'D..M' that are actually descendants of `D`, i.e.
+excluding `C` and `K`. This is exactly what the `--ancestry-path`
+option does. Applied to the 'D..M' range, it results in:
++
+-----------------------------------------------------------------------
+		E-------F
+		 \       \
+		  G---H---I---J
+			       \
+				L--M
+-----------------------------------------------------------------------
+
+The `--simplify-by-decoration` option allows you to view only the
+big picture of the topology of the history, by omitting commits
+that are not referenced by tags.  Commits are marked as !TREESAME
+(in other words, kept after history simplification rules described
+above) if (1) they are referenced by tags, or (2) they change the
+contents of the paths given on the command line.  All other
+commits are marked as TREESAME (subject to be simplified away).
+
+ifdef::git-rev-list[]
+Bisection Helpers
+~~~~~~~~~~~~~~~~~
+
+--bisect::
+	Limit output to the one commit object which is roughly halfway between
+	included and excluded commits. Note that the bad bisection ref
+	`refs/bisect/bad` is added to the included commits (if it
+	exists) and the good bisection refs `refs/bisect/good-*` are
+	added to the excluded commits (if they exist). Thus, supposing there
+	are no refs in `refs/bisect/`, if
++
+-----------------------------------------------------------------------
+	$ git rev-list --bisect foo ^bar ^baz
+-----------------------------------------------------------------------
++
+outputs 'midpoint', the output of the two commands
++
+-----------------------------------------------------------------------
+	$ git rev-list foo ^midpoint
+	$ git rev-list midpoint ^bar ^baz
+-----------------------------------------------------------------------
++
+would be of roughly the same length.  Finding the change which
+introduces a regression is thus reduced to a binary search: repeatedly
+generate and test new 'midpoint's until the commit chain is of length
+one. Cannot be combined with --first-parent.
+
+--bisect-vars::
+	This calculates the same as `--bisect`, except that refs in
+	`refs/bisect/` are not used, and except that this outputs
+	text ready to be eval'ed by the shell. These lines will assign the
+	name of the midpoint revision to the variable `bisect_rev`, and the
+	expected number of commits to be tested after `bisect_rev` is tested
+	to `bisect_nr`, the expected number of commits to be tested if
+	`bisect_rev` turns out to be good to `bisect_good`, the expected
+	number of commits to be tested if `bisect_rev` turns out to be bad to
+	`bisect_bad`, and the number of commits we are bisecting right now to
+	`bisect_all`.
+
+--bisect-all::
+	This outputs all the commit objects between the included and excluded
+	commits, ordered by their distance to the included and excluded
+	commits. Refs in `refs/bisect/` are not used. The farthest
+	from them is displayed first. (This is the only one displayed by
+	`--bisect`.)
++
+This is useful because it makes it easy to choose a good commit to
+test when you want to avoid to test some of them for some reason (they
+may not compile for example).
++
+This option can be used along with `--bisect-vars`, in this case,
+after all the sorted commit objects, there will be the same text as if
+`--bisect-vars` had been used alone.
+endif::git-rev-list[]
+
+
+Commit Ordering
+~~~~~~~~~~~~~~~
+
+By default, the commits are shown in reverse chronological order.
+
+--date-order::
+	Show no parents before all of its children are shown, but
+	otherwise show commits in the commit timestamp order.
+
+--author-date-order::
+	Show no parents before all of its children are shown, but
+	otherwise show commits in the author timestamp order.
+
+--topo-order::
+	Show no parents before all of its children are shown, and
+	avoid showing commits on multiple lines of history
+	intermixed.
++
+For example, in a commit history like this:
++
+----------------------------------------------------------------
+
+    ---1----2----4----7
+	\	       \
+	 3----5----6----8---
+
+----------------------------------------------------------------
++
+where the numbers denote the order of commit timestamps, `git
+rev-list` and friends with `--date-order` show the commits in the
+timestamp order: 8 7 6 5 4 3 2 1.
++
+With `--topo-order`, they would show 8 6 5 3 7 4 2 1 (or 8 7 4 2 6 5
+3 1); some older commits are shown before newer ones in order to
+avoid showing the commits from two parallel development track mixed
+together.
+
+--reverse::
+	Output the commits chosen to be shown (see Commit Limiting
+	section above) in reverse order. Cannot be combined with
+	`--walk-reflogs`.
+
+Object Traversal
+~~~~~~~~~~~~~~~~
+
+These options are mostly targeted for packing of Git repositories.
+
+ifdef::git-rev-list[]
+--objects::
+	Print the object IDs of any object referenced by the listed
+	commits.  `--objects foo ^bar` thus means ``send me
+	all object IDs which I need to download if I have the commit
+	object _bar_ but not _foo_''.
+
+--in-commit-order::
+	Print tree and blob ids in order of the commits. The tree
+	and blob ids are printed after they are first referenced
+	by a commit.
+
+--objects-edge::
+	Similar to `--objects`, but also print the IDs of excluded
+	commits prefixed with a ``-'' character.  This is used by
+	linkgit:git-pack-objects[1] to build a ``thin'' pack, which records
+	objects in deltified form based on objects contained in these
+	excluded commits to reduce network traffic.
+
+--objects-edge-aggressive::
+	Similar to `--objects-edge`, but it tries harder to find excluded
+	commits at the cost of increased time.  This is used instead of
+	`--objects-edge` to build ``thin'' packs for shallow repositories.
+
+--indexed-objects::
+	Pretend as if all trees and blobs used by the index are listed
+	on the command line.  Note that you probably want to use
+	`--objects`, too.
+
+--unpacked::
+	Only useful with `--objects`; print the object IDs that are not
+	in packs.
+
+--object-names::
+	Only useful with `--objects`; print the names of the object IDs
+	that are found. This is the default behavior.
+
+--no-object-names::
+	Only useful with `--objects`; does not print the names of the object
+	IDs that are found. This inverts `--object-names`. This flag allows
+	the output to be more easily parsed by commands such as
+	linkgit:git-cat-file[1].
+
+--filter=<filter-spec>::
+	Only useful with one of the `--objects*`; omits objects (usually
+	blobs) from the list of printed objects.  The '<filter-spec>'
+	may be one of the following:
++
+The form '--filter=blob:none' omits all blobs.
++
+The form '--filter=blob:limit=<n>[kmg]' omits blobs larger than n bytes
+or units.  n may be zero.  The suffixes k, m, and g can be used to name
+units in KiB, MiB, or GiB.  For example, 'blob:limit=1k' is the same
+as 'blob:limit=1024'.
++
+The form '--filter=sparse:oid=<blob-ish>' uses a sparse-checkout
+specification contained in the blob (or blob-expression) '<blob-ish>'
+to omit blobs that would not be not required for a sparse checkout on
+the requested refs.
++
+The form '--filter=tree:<depth>' omits all blobs and trees whose depth
+from the root tree is >= <depth> (minimum depth if an object is located
+at multiple depths in the commits traversed). <depth>=0 will not include
+any trees or blobs unless included explicitly in the command-line (or
+standard input when --stdin is used). <depth>=1 will include only the
+tree and blobs which are referenced directly by a commit reachable from
+<commit> or an explicitly-given object. <depth>=2 is like <depth>=1
+while also including trees and blobs one more level removed from an
+explicitly-given commit or tree.
++
+Note that the form '--filter=sparse:path=<path>' that wants to read
+from an arbitrary path on the filesystem has been dropped for security
+reasons.
+
+--no-filter::
+	Turn off any previous `--filter=` argument.
+
+--filter-print-omitted::
+	Only useful with `--filter=`; prints a list of the objects omitted
+	by the filter.  Object IDs are prefixed with a ``~'' character.
+
+--missing=<missing-action>::
+	A debug option to help with future "partial clone" development.
+	This option specifies how missing objects are handled.
++
+The form '--missing=error' requests that rev-list stop with an error if
+a missing object is encountered.  This is the default action.
++
+The form '--missing=allow-any' will allow object traversal to continue
+if a missing object is encountered.  Missing objects will silently be
+omitted from the results.
++
+The form '--missing=allow-promisor' is like 'allow-any', but will only
+allow object traversal to continue for EXPECTED promisor missing objects.
+Unexpected missing objects will raise an error.
++
+The form '--missing=print' is like 'allow-any', but will also print a
+list of the missing objects.  Object IDs are prefixed with a ``?'' character.
+
+--exclude-promisor-objects::
+	(For internal use only.)  Prefilter object traversal at
+	promisor boundary.  This is used with partial clone.  This is
+	stronger than `--missing=allow-promisor` because it limits the
+	traversal, rather than just silencing errors about missing
+	objects.
+endif::git-rev-list[]
+
+--no-walk[=(sorted|unsorted)]::
+	Only show the given commits, but do not traverse their ancestors.
+	This has no effect if a range is specified. If the argument
+	`unsorted` is given, the commits are shown in the order they were
+	given on the command line. Otherwise (if `sorted` or no argument
+	was given), the commits are shown in reverse chronological order
+	by commit time.
+	Cannot be combined with `--graph`.
+
+--do-walk::
+	Overrides a previous `--no-walk`.
+
+Commit Formatting
+~~~~~~~~~~~~~~~~~
+
+ifdef::git-rev-list[]
+Using these options, linkgit:git-rev-list[1] will act similar to the
+more specialized family of commit log tools: linkgit:git-log[1],
+linkgit:git-show[1], and linkgit:git-whatchanged[1]
+endif::git-rev-list[]
+
+include::pretty-options.txt[]
+
+--relative-date::
+	Synonym for `--date=relative`.
+
+--date=<format>::
+	Only takes effect for dates shown in human-readable format, such
+	as when using `--pretty`. `log.date` config variable sets a default
+	value for the log command's `--date` option. By default, dates
+	are shown in the original time zone (either committer's or
+	author's). If `-local` is appended to the format (e.g.,
+	`iso-local`), the user's local time zone is used instead.
++
+--
+`--date=relative` shows dates relative to the current time,
+e.g. ``2 hours ago''. The `-local` option has no effect for
+`--date=relative`.
+
+`--date=local` is an alias for `--date=default-local`.
+
+`--date=iso` (or `--date=iso8601`) shows timestamps in a ISO 8601-like format.
+The differences to the strict ISO 8601 format are:
+
+	- a space instead of the `T` date/time delimiter
+	- a space between time and time zone
+	- no colon between hours and minutes of the time zone
+
+`--date=iso-strict` (or `--date=iso8601-strict`) shows timestamps in strict
+ISO 8601 format.
+
+`--date=rfc` (or `--date=rfc2822`) shows timestamps in RFC 2822
+format, often found in email messages.
+
+`--date=short` shows only the date, but not the time, in `YYYY-MM-DD` format.
+
+`--date=raw` shows the date as seconds since the epoch (1970-01-01
+00:00:00 UTC), followed by a space, and then the timezone as an offset
+from UTC (a `+` or `-` with four digits; the first two are hours, and
+the second two are minutes). I.e., as if the timestamp were formatted
+with `strftime("%s %z")`).
+Note that the `-local` option does not affect the seconds-since-epoch
+value (which is always measured in UTC), but does switch the accompanying
+timezone value.
+
+`--date=human` shows the timezone if the timezone does not match the
+current time-zone, and doesn't print the whole date if that matches
+(ie skip printing year for dates that are "this year", but also skip
+the whole date itself if it's in the last few days and we can just say
+what weekday it was).  For older dates the hour and minute is also
+omitted.
+
+`--date=unix` shows the date as a Unix epoch timestamp (seconds since
+1970).  As with `--raw`, this is always in UTC and therefore `-local`
+has no effect.
+
+`--date=format:...` feeds the format `...` to your system `strftime`,
+except for %z and %Z, which are handled internally.
+Use `--date=format:%c` to show the date in your system locale's
+preferred format.  See the `strftime` manual for a complete list of
+format placeholders. When using `-local`, the correct syntax is
+`--date=format-local:...`.
+
+`--date=default` is the default format, and is similar to
+`--date=rfc2822`, with a few exceptions:
+--
+	- there is no comma after the day-of-week
+
+	- the time zone is omitted when the local time zone is used
+
+ifdef::git-rev-list[]
+--header::
+	Print the contents of the commit in raw-format; each record is
+	separated with a NUL character.
+endif::git-rev-list[]
+
+--parents::
+	Print also the parents of the commit (in the form "commit parent...").
+	Also enables parent rewriting, see 'History Simplification' above.
+
+--children::
+	Print also the children of the commit (in the form "commit child...").
+	Also enables parent rewriting, see 'History Simplification' above.
+
+ifdef::git-rev-list[]
+--timestamp::
+	Print the raw commit timestamp.
+endif::git-rev-list[]
+
+--left-right::
+	Mark which side of a symmetric difference a commit is reachable from.
+	Commits from the left side are prefixed with `<` and those from
+	the right with `>`.  If combined with `--boundary`, those
+	commits are prefixed with `-`.
++
+For example, if you have this topology:
++
+-----------------------------------------------------------------------
+	     y---b---b  branch B
+	    / \ /
+	   /   .
+	  /   / \
+	 o---x---a---a  branch A
+-----------------------------------------------------------------------
++
+you would get an output like this:
++
+-----------------------------------------------------------------------
+	$ git rev-list --left-right --boundary --pretty=oneline A...B
+
+	>bbbbbbb... 3rd on b
+	>bbbbbbb... 2nd on b
+	<aaaaaaa... 3rd on a
+	<aaaaaaa... 2nd on a
+	-yyyyyyy... 1st on b
+	-xxxxxxx... 1st on a
+-----------------------------------------------------------------------
+
+--graph::
+	Draw a text-based graphical representation of the commit history
+	on the left hand side of the output.  This may cause extra lines
+	to be printed in between commits, in order for the graph history
+	to be drawn properly.
+	Cannot be combined with `--no-walk`.
++
+This enables parent rewriting, see 'History Simplification' above.
++
+This implies the `--topo-order` option by default, but the
+`--date-order` option may also be specified.
+
+--show-linear-break[=<barrier>]::
+	When --graph is not used, all history branches are flattened
+	which can make it hard to see that the two consecutive commits
+	do not belong to a linear branch. This option puts a barrier
+	in between them in that case. If `<barrier>` is specified, it
+	is the string that will be shown instead of the default one.
+
+ifdef::git-rev-list[]
+--count::
+	Print a number stating how many commits would have been
+	listed, and suppress all other output.  When used together
+	with `--left-right`, instead print the counts for left and
+	right commits, separated by a tab. When used together with
+	`--cherry-mark`, omit patch equivalent commits from these
+	counts and print the count for equivalent commits separated
+	by a tab.
+endif::git-rev-list[]
+
+ifndef::git-rev-list[]
+Diff Formatting
+~~~~~~~~~~~~~~~
+
+Listed below are options that control the formatting of diff output.
+Some of them are specific to linkgit:git-rev-list[1], however other diff
+options may be given. See linkgit:git-diff-files[1] for more options.
+
+-c::
+	With this option, diff output for a merge commit
+	shows the differences from each of the parents to the merge result
+	simultaneously instead of showing pairwise diff between a parent
+	and the result one at a time. Furthermore, it lists only files
+	which were modified from all parents.
+
+--cc::
+	This flag implies the `-c` option and further compresses the
+	patch output by omitting uninteresting hunks whose contents in
+	the parents have only two variants and the merge result picks
+	one of them without modification.
+
+--combined-all-paths::
+	This flag causes combined diffs (used for merge commits) to
+	list the name of the file from all parents.  It thus only has
+	effect when -c or --cc are specified, and is likely only
+	useful if filename changes are detected (i.e. when either
+	rename or copy detection have been requested).
+
+-m::
+	This flag makes the merge commits show the full diff like
+	regular commits; for each merge parent, a separate log entry
+	and diff is generated. An exception is that only diff against
+	the first parent is shown when `--first-parent` option is given;
+	in that case, the output represents the changes the merge
+	brought _into_ the then-current branch.
+
+-r::
+	Show recursive diffs.
+
+-t::
+	Show the tree objects in the diff output. This implies `-r`.
