Could the defmfun macro be modified to make this work without changing
anything else? That would fix all such bugs.

Otherwise, $ratsimp could be a Maxima function (ratsimp(e,[v]) := ...)
that would call something like

(defmfun ratsimp (e vars) ...)

Using the #$ reader macro, it's possible to include Maxima code in
with Lisp. But when Maxima compiles rat3e.lisp, the #$ macro has not yet
been defined, I think--I didn't test this fix.
