I started implementing this which is when I realised that "end-\\1"
won't cut it because contents of the matched capture group must be
escaped with `regexp-quote'.  For example, if we had:

    ("verb\\(.\\)" . "\\1")

and a buffer had:

    verb\foo\

the end-regex for “verb\” would become just a single back-slash,
i.e. not a valid regex.
