Implement an `align` atom which left-, middle-, or right-aligns the content between %(align:...) and %(end). The "align:" is followed by `<width>` and `<position>` in any order separated by a comma, where the `<position>` is either left, right or middle, default being left and `<width>` is the total length of the content with alignment. If the contents length is more than the width then no alignment is performed. e.g. to align a refname atom to the middle with a total width of 40 we can do: --format="%(align:middle,40)%(refname)%(end)". We introduce an `at_end` function for each element of the stack which is to be called when the `end` atom is encountered. Using this we implement end_align_handler() for the `align` atom, this aligns the final strbuf by calling `strbuf_utf8_align()` from utf8.c. Ensure that quote formatting is performed on the whole of %(align:...)...%(end) rather than individual atoms inside. We skip quote formatting for individual atoms when the current stack element is handling an %(align:...) atom and perform quote formatting at the end when we encounter the %(end) atom of the second element of then stack. Add documentation and tests for the same.

Git - the stupid content tracker
////////////////////////////////////////////////////////////////
"git" can mean anything, 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
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.
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).
Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.
The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org (read
Documentation/SubmittingPatches for instructions on patch submission).
To subscribe to the list, send an email with just "subscribe git" in
the body to majordomo@vger.kernel.org. The mailing list archives are
available at http://news.gmane.org/gmane.comp.version-control.git/,
http://marc.info/?l=git and other archival sites.
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.
