Summary: scanmap(minfactorial,a!) infinite loop

Initial Comment:
scanmap(minfactorial,a!) gets into an infinite loop (recursion) and crashes Maxima.

This appears to be because minfactorial returns an unsimplified result (observed with ?trace(minfactorial)), and scanmap doesn't simplify it before recursing.

scanmap(lambda([x],minfactorial(x)),a!) does not have this problem, because meval simplifies the result.
