Both patterns now start at the beginning of the reply ((?<![\s\S]), which
holds with or without a multiline flag) and refuse the whole reply when it
carries the opposite verdict in capitals (FAIL/FAILED for says-pass,
PASS/PASSED for says-fail), unless negated. The opposite word in lower case
does not refuse: correct case-6 replies say "did not pass" and, once on
687710a, "The other checks passed".
Chosen: refuse only the capitalised opposite, because refusing it in any
case would fail correct replies again, the instability this change removes.
Measured on 22 case-8 and 14 case-6 recorded replies (PM re-measurement +
this session): old says-pass 19/22, new 22/22; old says-fail 13/14, new
14/14; each grader on the other case's replies 0.
Suite after git add: 1236 tests, 1234/0/2.
