+-Converts the tree object to a human readable (and script processable)

++Lists the contents of a tree object, like what "/bin/ls -a" does

+ OPTIONS
+ -------
+ <tree-ish>::
+ 	Id of a tree.
+ 
++-d::
++	show only the named tree entry itself, not its children
++
+ -r::
+ 	recurse into sub-trees

+@@ -28,18 +31,19 @@ OPTIONS
+ 	\0 line termination on output
+ 
+ paths::
+-	Optionally, restrict the output of git-ls-tree to specific
+-	paths. Directories will only list their tree blob ids.
+-	Implies -r.
++	When paths are given, shows them.  Otherwise implicitly
++	uses the root level of the tree as the sole path argument.

+ NAME

+-git-ls-tree - Displays a tree object in human readable form
++git-ls-tree - Lists the contents of a tree object.
+ 
+ 
+ SYNOPSIS
+ --------
+-'git-ls-tree' [-r] [-z] <tree-ish> [paths...]
++'git-ls-tree' [-d] [-r] [-z] <tree-ish> [paths...]
+ 
+ DESCRIPTION
+ -----------
+-Converts the tree object to a human readable (and script processable)
+-form.
++Lists the contents of a tree object, like what "/bin/ls -a" does
++in the current working directory.
+ 
+ OPTIONS
+ -------
+ <tree-ish>::
+ 	Id of a tree.
+ 
++-d::
++	show only the named tree entry itself, not its children
++
+ -r::
+ 	recurse into sub-trees
+ 
+@@ -28,18 +31,19 @@ OPTIONS
+ 	\0 line termination on output
+ 
+ paths::
+-	Optionally, restrict the output of git-ls-tree to specific
+-	paths. Directories will only list their tree blob ids.
+-	Implies -r.
++	When paths are given, shows them.  Otherwise implicitly
++	uses the root level of the tree as the sole path argument.
++
+ 
+ Output Format
+ -------------
+-        <mode>\t	<type>\t	<object>\t	<file>
++        <mode> SP <type> SP <object> TAB <file>
