If that's enough to shut compilers up, +1 from me.  MSVC 7.1 doesn't
whine even with no tricks.

I do want to keep the two optimizations in list.pop(), which consist
of not test+branch'ing the return values of two calls that have been
proved safe.  But things change over time, and in a debug build I do
want to assert that they are in fact safe.

I originally did this with a pile of #ifdef Py_DEBUG blocks, but (as
the original checkin comment said) that was even uglier than the
comma-expression hack.
