# This function can be used to access a tokenized list of words
# on the command line:
#
# __git_reassemble_comp_words_by_ref '=:'
# if test "${words_[cword_-1]}" = -w
# then
# ...
# fi
#
# The argument should be a collection of characters from the list of
# word completion separators (COMP_WORDBREAKS) to treat as ordinary
# characters.
#
# This is roughly equivalent to going back in time and setting
# COMP_WORDBREAKS to exclude those characters. The intent is to
# make option types like --date=<type> and <rev>:<path> easy to
# recognize by treating each shell word as a single token.
#
# It is best not to set COMP_WORDBREAKS directly because the value is
# shared with other completion scripts. By the time the completion
# function gets called, COMP_WORDS has already been populated so local
# changes to COMP_WORDBREAKS have no effect.
#
# Output: words_, cword_, cur_.
