Junio C Hamano 690d8824c8 Contributed bash completion support for core Git tools.
This is a set of bash completion routines for many of the
popular core Git tools.  I wrote these routines from scratch
after reading the git-compl and git-compl-lib routines available
from the gitcompletion package at http://gitweb.hawaga.org.uk/
and found those to be lacking in functionality for some commands.
Consequently there may be some similarities but many differences.

Since these are completion routines only for tools shipped with
core Git and since bash is a popular shell on many of the native
core Git platforms (Linux, Mac OS X, Solaris, BSD) including these
routines as part of the stock package would probably be convienent
for many users.

# bash completion support for core Git.
#
# Copyright (C) 2006 Shawn Pearce
# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
#
# The contained completion routines provide support for completing:
#
# *) local and remote branch names
# *) local and remote tag names
# *) .git/remotes file names
# *) git 'subcommands'
# *) tree paths within 'ref:path/to/file' expressions
#
# To use these routines:
#
# 1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
# 2) Added the following line to your .bashrc:
# source ~/.git-completion.sh
#
