The simplifier for the Gamma function calls bffac but not cbffac. So I did not
see that there is a function cbffac too. Perhaps we should extend the code of
the Gamma function to use the Complex version too.
It might be even better to write both algorithm in Lisp and add them to the file
csimp2.lisp.
