[GiNaC-devel] Simplifying powers

[Vladimir V. Kisil]

	Dear All,

	I propose a patch to power::expand(). It does not affect
  power::eval() and automatic rewriting rules. The patch expand
  expressions like (a*b*p)^c to (a*b)^c*p^c if p is positive and c is
  real. A simple check is added as well.

  Best wishes,
  Vladimir
