Comment (by dsm):
Ah, those were merely mirroring the +oo cases. Really they were only
testing whether the negation worked; it was the integral test which was
really verifying the success. However, we can test it explicitly by
adding.
{{{
sage: bool((-oo)._sympy_() == -sympy.oo)
True
}}}
which fails without the patch. Modified to incorporate this.
