The case 0^0 is one of those things you can make up your own mind about.
Maple and MuPAD return 1, and so 0^0-0^0 returns 0, whereas Mathematica
returns undefined. It may be possible for it to return undefined, unless a
user flag ("zeroexp", for example) is set, in which case it returns 1. I
don't particularly care either way.
