Revised patch: Power transformation for real base and positive exponent
Dear All, I am attaching the revised patch to power::expand(), which make the transformation: (x*p)^c --> x^c * p^c, if p>0 and c is real This seems to be helpful in many cases. A corresponding check is added as well. Best wishes, Vladimir -- Vladimir V.

One question about your patch for expand(): Is the fact that c is real really essential for this transformation? Best wishes -richy. -- Richard B. Kreckel <http://in.terlu.de/~kreckel/>

You seems, to be right, Richard: I cannot find a reason why it is wrong for a complex c. I was overcautious. I am attaching the corrected patch. Best wishes, Vladimir -- Vladimir V.
