Let's see...  this basically ends up calling `read-regexp', which then
calls `read-from-minibuffer'.

The blinking is done from `blink-matching-open', which does a
`(forward-sexp -1)' to find the position.

So we'd have to set up some syntax stuff to get this right.  Does
anybody know if we have something ready-made for regexps somewhere?
