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.

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
116 # function gets called, COMP_WORDS has already been populated so local
