Comment:
Ok, LGTM. I took the liberty of squashing your three patches and rebasing
the whole on top of `develop`; please protest if you disagree.
I had a doubt about the fact of computing the quotient (possibly as a
Laurent series) in all cases and then checking that it was in fact a power
series, but at least it helps keeping the logic that decides whether the
quotient fo two power series is a power series in a single place.
