Comment:
This is a duplicate of #9880. With [https://bitbucket.org/burcin/pynac-
patches/src the Pynac patch queue] and patches listed on #9880, I get:
{{{
sage: var('a b x y z')
(a, b, x, y, z)
sage: p = -a*x^3 - a*x*y^2 + 2*b*x^2*y + 2*y^3 + x^2*z + y^2*z + x^2 + y^2
+ a>
sage: p.collect(x)
-a*x^3 + (2*b*y + z + 1)*x^2 + 2*y^3 + y^2*z - (a*y^2 - a)*x + y^2
}}}
We should close this after adding it as a doctest to #9880.
