vercmp: always return 0 if we perform a compare
And change the wording slightly to indicate we *print* a value, not *return* it. You can't return negative values (they get coerced to 255), so it isn't worth it to try and cram the result into the return code. Acked-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
