Update of /home/cvs/GiNaC/ginac

Modified Files: power.cpp Log Message: expand() always expands the exponent and transforms x^(a+b) -> x^a*x^b

Question, Sir: Now, that we have expand(x^((a+b)^2-a^2-b^2-2*a*b)) -> 1, wouldn't it be natural to also have normal(x^((x^2+2*x*y+y^2)/(x+y)^2)) -> x? Or does this contradict the "first make a polynomial out of it" principle? -richy. -- Richard Kreckel <Richard.Kreckel@Uni-Mainz.DE> <http://wwwthep.physik.uni-mainz.de/~kreckel/>
