   4# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
   5# Distributed under the GNU General Public License, version 2.0.
   6#
   7# The contained completion routines provide support for completing:
   8#
   9#    *) local and remote branch names
  10#    *) local and remote tag names
  11#    *) .git/remotes file names
  12#    *) git 'subcommands'
  13#    *) git email aliases for git-send-email
  14#    *) tree paths within 'ref:path/to/file' expressions
  15#    *) file paths within current working directory and index
  16#    *) common --long-options
  17#
  18# To use these routines:
  19#
  20#    1) Copy this file to somewhere (e.g. ~/.git-completion.bash).
  21#    2) Add the following line to your .bashrc/.zshrc:
  22#        source ~/.git-completion.bash
  23#    3) Consider changing your PS1 to also show the current branch,
  24#       see git-prompt.sh for details.
  25#
  26# If you use complex aliases of form '!f() { ... }; f', you can use the null
  27# command ':' as the first command in the function body to declare the desired
  28# completion style.  For example '!f() { : git commit ; ... }; f' will
  29# tell the completion to use commit completion.  This also works with aliases
  30# of form "!sh -c '...'".  For example, "!sh -c ': git commit ; ... '".
  31#
  32# Compatible with bash 3.2.57.
  33#
  34# You can set the following environment variables to influence the behavior of
  35# the completion routines:
  36#
  37#   GIT_COMPLETION_CHECKOUT_NO_GUESS
  38#
  39#     When set to "1", do not include "DWIM" suggestions in git-checkout
  40#     completion (e.g., completing "foo" when "origin/foo" exists).

 135# characters.
 136#
 137# This is roughly equivalent to going back in time and setting
