   This sounds a lot like the find-file-at-point (ffap) facility of
   Emacs.

It does indeed.

   FFAP-AT-MOUSE is bound to Shift + right mouse.

Maybe this would be a better default gesture?  But in that case I'd
better be sure that ilisp-mouse.el is a strict superset of ffap.  (And
in any case, I'd be sorry to see the traditional Meta-Left go.)

   So maybe you can simply integrate your new EDIT-DEFINITION code into
   ffap?

Actually, my original patch uses ffap-file-at-point in order to leverage
ffap's parsing cleverness.  But I see now that I should be calling
ffap-guesser instead.  Thanks for the heads-up.

   As you can see, I'm not familiar with the innards of ffap; I've used
it for quite a while, but only superficially.  However, I do note that
the grunt lexing work is done by ffap-string-at-point, which seems to be
biased toward identifier-like tokens.  Since I can't see an easy way to
integrate the ilisp-mouse.el code that deals with S-expression names, it
is probably easier to keep it as a wrapper around ffap.  In any case, I
will look into better integration with ffap, at least at the level of
customization.
