Nope, the thing to do was to read the docs for _PyLong_AsScaledDouble,
which explicitly promise e >= 0. That's what I did :-) "The docs"
are in longobject.h. You can tell which functions I wrote, BTW,
because they're the ones with comments in the header file documenting
what they do. It's an ongoing mystery to me why nobody else found
that to be a practice worth emulating ;-)/:-(
