+# 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_.
