Comment (by zimmerma):
Alex,
in fact I guess your initial patch did what we want. Indeed with your
latest example:
{{{
sage: g=f/2
sage: g.parent()
Univariate Polynomial Ring in x over Power Series Ring in d over
Univariate Polynomial Ring in c over Multivariate Polynomial Ring in a, b
over Rational Field
}}}
thus the fact of dividing f by an element of the base ring automatically
extends it to the corresponding
fraction field if necessary.
Thus I suggest you revert to your first patch (sorry) and add the above
example as test.
Paul
