  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.

 107 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
 108 # characters.
 109 #
