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

 110 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
 111 # characters.
 112 #
