Yuck.  Thanks to Douglas Crosher, cmucl and scl have unspecial
support.  I suspect the same or very similar solution will work for
sbcl.  We should ask the clisp people if there's a similar function.

In the mean time, I think I'll look through plot.lisp and change all
uses of f to something else.  Or look at cpoly and ratout to see if we
can at least change f to *f* for those files.

I think getting rid of these special variables, or at least making
them use the * convention is an important task that we should try to
do whenever possible.  I, for one, get totally confused when a special
variable is used as a parameter to a function.

I thought that if f were special, describe would say so.  CMUCL
normally says so.  (But it didn't on my build because the version I
have has unspecial support for cmucl.)

Thanks for trying this out for me.
