   9 # The contained completion routines provide support for completing:
  10 #
  11 #    *) local and remote branch names
  12 #    *) local and remote tag names
  13 #    *) .git/remotes file names
  14 #    *) git 'subcommands'
  15 #    *) tree paths within 'ref:path/to/file' expressions
  16 #    *) common --long-options
  17 #
  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.

 100 # This function can be used to access a tokenized list of words
 101 # on the command line:

 104 #       if test "${words_[cword_-1]}" = -w

 109 # The argument should be a collection of characters from the list of
 110 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
 111 # characters.
 112 #
 113 # This is roughly equivalent to going back in time and setting
 114 # COMP_WORDBREAKS to exclude those characters.  The intent is to
 115 # make option types like --date=<type> and <rev>:<path> easy to
 116 # recognize by treating each shell word as a single token.
 117 #
 118 # It is best not to set COMP_WORDBREAKS directly because the value is
 119 # shared with other completion scripts.  By the time the completion
 120 # function gets called, COMP_WORDS has already been populated so local
 121 # changes to COMP_WORDBREAKS have no effect.
