[GiNaC-list] That series again

Using the new 1.2.3, in ginsh: 

> series((1+x)^y,x,5);


> series(exp(y*log(1+x)),x,5);

My understanding is the latter is correct as it gives 1/n! the Stirling1
triangle and substituting a number for y gives binomial coefficients.
Maybe any expansion of a power can be expressed by such a construction,
even in the GiNaC source, so a patch would be straightforward?
