Comment (by SimonKing):
Sorry, I just made another change: Around line 1018, I ask: "How can we
establish a coercion from `P` to `\mathrm{Frac}(\ZZ[x])`?"
But actually, in the end we do ''not'' establish such a coercion. Instead,
we make Sage create a third parent into which both P and `Frac(ZZ['x']`
coerce. I commented accordingly in the new patch version.
