Non-blocking points of the second review of PR #47: refusing 65535, and
dropping the end anchor of the pattern, both left the suite green.
- Ports 1 and 65535 must be accepted. Given to both variables at once,
so the run stops on the "must differ" refusal, which comes after the
range check, and nothing listens on a port fixed in advance.
- "80abc" must be refused, on each variable.
