  16 #    *) file paths within current working directory and index
  17 #    *) common --long-options
  18 #
  19 # To use these routines:
  20 #
  21 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
  22 #    2) Add the following line to your .bashrc/.zshrc:
  23 #        source ~/.git-completion.sh
  24 #    3) Consider changing your PS1 to also show the current branch,
  25 #       see git-prompt.sh for details.

  94 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
  95 # characters.
  96 #
  97 # This is roughly equivalent to going back in time and setting
  98 # COMP_WORDBREAKS to exclude those characters.  The intent is to
  99 # make option types like --date=<type> and <rev>:<path> easy to
 100 # recognize by treating each shell word as a single token.

 103 # shared with other completion scripts.  By the time the completion
 104 # function gets called, COMP_WORDS has already been populated so local
 105 # changes to COMP_WORDBREAKS have no effect.
