Bash's programmable completion provides the COMP_WORDS array variable, which holds the individual words in the current command line. In bash versions prior to v4 "words are split on shell metacharacters as the shell parser would separate them" (quote from bash v3.2.48's man page). This behavior has changed with bash v4, and the command line "is split into words as readline would split it, using COMP_WORDBREAKS as" "the set of characters that the readline library treats as word separators" (quote from bash v4's man page). Since COMP_WORDBREAKS contains the characters : and = by default, this behavior change in bash affects git's completion script. For example, before bash 4, running $ git log --pretty=m <tab><tab> would give a list of pretty-printing formats starting with 'm' but now it completes on branch names. It would be possible to work around this by removing '=' and ':' from COMP_WORDBREAKS, but as noticed in v1.5.6.4~9^2 (bash completion: Resolve git show ref:path<tab> losing ref: portion, 2008-07-15), that would break *other* completion scripts. The bash-completion library includes a better workaround: the _get_comp_words_by_ref function re-assembles a copy of COMP_WORDS, excluding a collection of word separators of the caller's choice. Use it. As a bonus, this also improves behavior when tab is pressed with the cursor in the middle of a word. To avoid breaking setups with the bash-completion library not already loaded, if the _get_comp_words_by_ref function is not defined then a shim that just reads COMP_WORDS will be used instead (no change from the current behavior in that case).

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.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.
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. 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://marc.theaimsgroup.com/?l=git and other archival sites.
The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
