revert(3p/git): Revert merge of git upstream at v2.26.2 r/852

This causes cgit to serve error pages, which is undesirable.

This reverts commit 5229c9b232de5bfa959ad6ebbb4c8192ac513352, reversing
changes made to f2b211131f2347342dde63975b09cf603149f1a3.

 --------------
 
 You can write your own custom helpers to interface with any system in
-which you keep credentials.
-
-Credential helpers are programs executed by Git to fetch or save
-credentials from and to long-term storage (where "long-term" is simply
-longer than a single Git process; e.g., credentials may be stored
-in-memory for a few minutes, or indefinitely on disk).
-
-Each helper is specified by a single string in the configuration
-variable `credential.helper` (and others, see linkgit:git-config[1]).
-The string is transformed by Git into a command to be executed using
-these rules:
-
-  1. If the helper string begins with "!", it is considered a shell
-     snippet, and everything after the "!" becomes the command.
-
-  2. Otherwise, if the helper string begins with an absolute path, the
-     verbatim helper string becomes the command.
-
-  3. Otherwise, the string "git credential-" is prepended to the helper
-     string, and the result becomes the command.
-
-The resulting command then has an "operation" argument appended to it
-(see below for details), and the result is executed by the shell.
-
-Here are some example specifications:
-
-----------------------------------------------------
-# run "git credential-foo"
-foo
-
-# same as above, but pass an argument to the helper
-foo --bar=baz
-
-# the arguments are parsed by the shell, so use shell
-# quoting if necessary
-foo --bar="whitespace arg"
-
-# you can also use an absolute path, which will not use the git wrapper
-/path/to/my/helper --with-arguments
-
-# or you can specify your own shell snippet
-!f() { echo "password=`cat $HOME/.secret`"; }; f
-----------------------------------------------------
-
-Generally speaking, rule (3) above is the simplest for users to specify.
-Authors of credential helpers should make an effort to assist their
-users by naming their program "git-credential-$NAME", and putting it in
-the `$PATH` or `$GIT_EXEC_PATH` during installation, which will allow a
-user to enable it with `git config credential.helper $NAME`.
-
-When a helper is executed, it will have one "operation" argument
-appended to its command line, which is one of:
-
-`get`::
-
-	Return a matching credential, if any exists.
-
-`store`::
-
-	Store the credential, if applicable to the helper.
-
-`erase`::
-
-	Remove a matching credential, if any, from the helper's storage.
-
-The details of the credential will be provided on the helper's stdin
-stream. The exact format is the same as the input/output format of the
-`git credential` plumbing command (see the section `INPUT/OUTPUT
-FORMAT` in linkgit:git-credential[1] for a detailed specification).
-
-For a `get` operation, the helper should produce a list of attributes on
-stdout in the same format (see linkgit:git-credential[1] for common
-attributes). A helper is free to produce a subset, or even no values at
-all if it has nothing useful to provide. Any provided attributes will
-overwrite those already known about by Git.  If a helper outputs a
-`quit` attribute with a value of `true` or `1`, no further helpers will
-be consulted, nor will the user be prompted (if no credential has been
-provided, the operation will then fail).
-
-For a `store` or `erase` operation, the helper's output is ignored.
-If it fails to perform the requested operation, it may complain to
-stderr to inform the user. If it does not support the requested
-operation (e.g., a read-only store), it should silently ignore the
-request.
-
-If a helper receives any other operation, it should silently ignore the
-request. This leaves room for future operations to be added (older
-helpers will just ignore the new requests).
