What

This adds 6 tests to specs/claw/suggest.t27. The mutation sweep of #10673 left 16 surviving mutants on its code lines, and these tests kill all 16.

Test Mutants it kills
each_byte_of_the_extension_is_checked path_is_t27 return false to return true on the '2' and the '7' (a.t37, a.t28)

Verification (Railway lab)

  • t27c test-report specs/claw/suggest.t27: 22 tests, 22 pass, 0 vacuous passes.
  • t27b test: 22 tests pass.
  • I re-ran the 16 survivors one at a time: 16 caught, 0 survived, 0 blocked. Classification reads the report's FAIL line.
  • seal --save for suggest, then seal --verify on all 31 claw specs: 31 match, 0 differ.

Closes #10678

Six tests: the digit 9 and seven-digit numbers in a hunk header, each
single-byte header fault refused without a write, both extension bytes
of a .t27 path, a one-line diff range, hunks sharing one line read from
the later side, and should_post(1).

Closes #10678
