What I don't understand:
Why are there two functions, factorial and gamma?
Is there a different pragmatics behind it?
If not, shouldn't the simplifications yield the same?
And if one is going for "maximal strength" simplification,
shouldn't one always apply makefact, since apparently
Maxima understands factorial better than gamma?
