Hmm, on second thought, this will break the following case, in bash:

	. /etc/bash_completion;	# defines _get_comp_words_by_ref
	. contrib/completion/git-completion.bash

Not sure how to salvage that.  Maybe we need a git-specific API
that wraps _get_comp_words_by_ref when the latter is available.

	if type _get_comp_words_by_ref >/dev/null 2>&1; then
		_git_get_comp_words_by_ref () {
			_get_comp_words_by_ref "$@"
			if test "${words+set}"
			then
				cword="${words[@]}"
			fi
		}
	else
		_git_get_comp_words_by_ref () {
			...
		}
	fi
