Pure paranoia that the compiler might not optimize this to the separate
instructions (and in that case I would feel the call overhead in this
presumably not-too-cold code path to be too large). I have that paranoia
even though I'm a compiler engineer. Or maybe because of it :) It's
probably better to use strcmp anyway, right ;)
