See testcase. We must always paste tokens (at least if not currently substing a normal argument, which is a speed optimization only now) but at the same time must not regard a ## token coming from argument expansion as the token-paste operator, nor if we constructed a ## token due to pasting itself (that was already checked by pp/01.c).
