__git_ps1() finds out the path to the repository by using the __gitdir() helper function. __gitdir() is basically just a wrapper around 'git rev-parse --git-dir', extended with support for recognizing a remote repository given as argument, to use the path given on the command line, and with a few shortcuts to recognize a git repository in cwd or at $GIT_DIR quickly without actually running 'git rev-parse'. However, the former two is only necessary for the completion script but makes no sense for the bash prompt, while the latter shortcuts are performance optimizations __git_ps1() can do without (they just avoid the overhead of fork()+exec()ing a git process). Run 'git rev-parse --git-dir' directly in __git_ps1(), because it will allow this patch series to combine several $(git rev-parse ...) command substitutions in the main code path, and the overall performance benefit will far outweigh the loss of those few shortcuts in __gitdir(). Furthermore, since __gitdir() is not needed anymore for the prompt, remove it from the prompt script finally eliminating its duplication between the prompt and completion scripts. Also remove the comment from the completion script warning about this code duplication. Signed-off-by: SZEDER Gábor <szeder@ira.uka.de>

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/everyday.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.
