It's NOT 2s complement, though. It's 2s complement if you're working
with integer loops, but it's signed magnitude if you're working with
floating point, and Lua doesn't tell you explicitly which you're
working with unless you ask. So it's already "signed magnitude, except
when it's 2s complement" and Paige's patch brings it just a little bit
closer to "always signed magnitude".
