Hmm, it seems that way.  Could you post a comment on the tracker issue
about that, please?

I'm not sure why the original changeset went in, but I agree it looks
as though it's no longer necessary.  Certainly there should be enough
-0.0 versus 0.0 tests around to detect any issues, so if all the tests
pass with the extra PyObject_IsTrue check disabled then there probably
isn't a problem.
