  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.

 106 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
 107 # characters.
 108 #
 109 # This is roughly equivalent to going back in time and setting
 110 # COMP_WORDBREAKS to exclude those characters.  The intent is to
 111 # make option types like --date=<type> and <rev>:<path> easy to
 112 # recognize by treating each shell word as a single token.
 113 #
 114 # It is best not to set COMP_WORDBREAKS directly because the value is
 115 # shared with other completion scripts.  By the time the completion
