There are two criteria that I use here. I'll often tend towards the
positive test; it's just that little bit easier to comprehend, I
think. On the other hand, if one case is overwhelmingly more common,
I'll usually put that first even if it does mean using a negative
test.

I'm not buying the short-case-first argument. If the code in a case
block is long enough for that to matter, it really belongs in a
function of its own anyway.
