"""R-364: hu_grep.py never reports an untested zero for an accented pattern.

Each case asserts the CONSEQUENCE an operator would act on: a present string is counted; a transformed
pattern, a blind instrument, or a normal-form mismatch is REFUSED (exit 2), never a quiet 0; and a real
absence, with every control behaving, is a 0 (exit 1). Pure Python — runs on the BusyBox CI runner.
