Exactly. However, while I'd like to guarantee that abs(x) >= 0, the
truth is that numpy is "close to the metal" in a lot of ways, and anyone
should know that the arithmetic of integers near max and minimum values
is fraught with danger.
If we don't change the type, then any number other than MIN_INT works
correctly. I think more code will break by silently going from a signed
to a signed type than that one value being weird.
