Comment:
I confirm the rebased patch applies cleanly to sage-5.0.beta10.
However there is still an issue:
{{{
sage: R.<x> = ZZ[]
sage: R(0).integral().parent()
Univariate Polynomial Ring in x over Integer Ring
sage: R(3).integral().parent()
Univariate Polynomial Ring in x over Rational Field
}}}
Why do we get a different parent for zero?
