The function, commit_rewrite_person(), is designed to find and replace
an ident string in the header part, and the way it avoids a random
occurrence of "author A U Thor <author@example.com" in the text is by
insisting "author" to appear at the beginning of line by passing
"\nauthor " as "what".
The implementation also doesn't make any effort to limit itself to the
commit header by locating the blank line that appears after the header
part and stopping the search there. Also, the interface forces the
caller to make multiple calls if it wants to rewrite idents on multiple
headers. It shouldn't be the case.
To support the existing caller better, update commit_rewrite_person()
to:
- Make a single pass in the input buffer to locate headers named
"author" and "committer" and replace idents on them.
- Stop at the end of the header, ensuring that nothing in the body of
the commit object is modified.
The return type of the function commit_rewrite_person() has also been
changed from int to void. This has been done because the caller of the
function doesn't do anything with the return value of the function.
By simplifying the interface of the commit_rewrite_person(), we also
intend to expose it as a public function. We will also be renaming the
function in a future commit to a different name which clearly tells that
the function replaces idents in the header of the commit buffer.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.
Git is an Open Source project covered by the GNU General Public
License version 2 (some parts of it are under different licenses,
compatible with the GPLv2). It was originally written by Linus
Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/
including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
Issues which are security relevant should be disclosed privately to
the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that
list the current status of various development topics to the mailing
list. The discussion following them give a good reference for
project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very
first version. He described the tool as "the stupid content tracker"
and the name as (depending on your mood):
random three-letter combination that is pronounceable, and not
actually used by any common UNIX command. The fact that it is a
mispronunciation of "get" may or may not be relevant.
stupid. contemptible and despicable. simple. Take your pick from the
dictionary of slang.
"global information tracker": you're in a good mood, and it actually
works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
