   7 # The contained completion routines provide support for completing:

  10 #    *) local and remote tag names
  11 #    *) .git/remotes file names
  12 #    *) git 'subcommands'
  13 #    *) tree paths within 'ref:path/to/file' expressions
  14 #    *) file paths within current working directory and index
  15 #    *) common --long-options
  16 #
  17 # To use these routines:
  18 #
  19 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
  20 #    2) Add the following line to your .bashrc/.zshrc:
  21 #        source ~/.git-completion.sh
  22 #    3) Consider changing your PS1 to also show the current branch,
  23 #       see git-prompt.sh for details.

  90 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
  91 # characters.
  92 #
  93 # This is roughly equivalent to going back in time and setting
  94 # COMP_WORDBREAKS to exclude those characters.  The intent is to
  95 # make option types like --date=<type> and <rev>:<path> easy to
  96 # recognize by treating each shell word as a single token.

  98 # It is best not to set COMP_WORDBREAKS directly because the value is
  99 # shared with other completion scripts.  By the time the completion
