…atedNS ffStrbufMatchSeparatedNS takes an explicit compLength and is the length-bounded variant behind ffStrbufMatchSeparatedS; the Linux keyboard handler calls it with a fixed-size buffer length rather than a NUL-terminated string. tests/strbuf.c only exercised the S wrapper, so the bounded contract had no coverage: bounds cutting mid-token, compLength=0, embedded NUL inside bounds, and empty-substring matching were all untested, and a regression in the bounded path would keep every existing test green. Add a focused block asserting twelve length-boundary cases.

Adds a focused test block for
ffStrbufMatchSeparatedNS, the length-bounded variant behindffStrbufMatchSeparatedS.Why
The Linux keyboard handler calls the NS variant with a fixed-size buffer length rather than a NUL-terminated string, but
tests/strbuf.conly exercised the S wrapper — the bounded contract had zero coverage. The new block asserts twelve length-boundary cases: bounds cutting mid-token (match vs no-match),compLength = 0, a bound spanning exactly one token, no separator in bounds, an embedded NUL inside the bounds, and empty-substring matching, all against the current implementation semantics.Tested
cmake -DFF_BUILD_TESTS=on→ffstrbuf_test(block verified against the implementation's branch behavior; full suite runs in CI).
