Summary: minfactorial doesn't look inside "!"

Initial Comment:
The minfactorial function doesn't look inside the
factorial function. So it misses some simplifications
that it could do:

(%i1) (n!/(n-1)!)!;
(%o1) (n!/(n-1)!)!
(%i2) minfactorial(%);
(%o2) (n!/(n-1)!)!  <-- could be n!

(%i3) build_info();
Maxima version: 5.9.3
Maxima build date: 0:52 3/20/2006
host type: i686-pc-mingw32
lisp-implementation-type: GNU Common Lisp (GCL)
