I don't think this is right.
{{{
if self.degree() == 0:
return Factorization([(self,1)])
}}}
If R (the coefficient ring) is a field then we should return the
factorization with no pairs (irreducible,exponent) but with unit=self.
But if (for example) R is ZZ then we do need to factor constants, so
returning self(0).factor() is about right.
