[GiNaC-devel] Fixed bug in power::expand_mul, but .....

Dear all, I fixed a bug in power::expand_mul by calling the method mul::combine_pair_with_coeff_to_pair from this function. However, the comments are strongly discouraging. They say, as you can read in the source: "it is safe not to call mul::combine_pair_with_coeff_to_pair() since n is an integer". So, basically I am rather rudely ignoring the comments, but I really don't understand what is unsafe about this method, so maybe someone can enlighten me. Many thanks, Chris
