Thanks to everybody who helped improve that code with "obvious" changes
that weren't obvious to me. I installed the attached patches to try to
incorporate all the comments. I'm not sure what to do about
footnote.el's blithe overuse of "+" and "*" so I merely left a FIXME
comment for that, stealing its wording from Mattias's email.

I avoided regexp-opt before because its doc string implied that
(regexp-opt '("a" "a")) was invalid. The first patch attempts to fix
that confusion too.
