I think the usual convention is to test for < 0, unless there are other
negative return values that are legal. This is doubtless a silly
cycle-shaving habit (on nearly all machines, test against 0 is a bit
more compact than test against other constants), but it is a widespread
habit anyway, and if you sometimes do it one way and sometimes another
you just create a distraction for readers.
