Probably some of each. In just scanning though some other code, another
case I saw was comparing characters to #"\000".

I just added it. It hasn't triggered many on the few quick programs I ran
it through, but I'll see how it does on a self compile. It's not
triggering any false-positives, so it shouldn't hurt performance to leave
it in.
