Move the tests for "-f <file>" where "<file>" contains a NUL byte pattern into their own file. I added most of these tests in966be95549("grep: add tests to fix blind spots with \0 patterns", 2017-05-20). Whether a regex engine supports matching binary content is very different from whether it matches binary patterns. Since2f8952250a("regex: add regexec_buf() that can work on a non NUL-terminated string", 2016-09-21) we've required REG_STARTEND of our regex engines so we can match binary content, but only the PCRE v2 engine can sensibly match binary patterns. Since9eceddeec6("Use kwset in grep", 2011-08-21) we've been punting patterns containing NUL-byte and considering them fixed, except in cases where "--ignore-case" is provided and they're non-ASCII, see5c1ebcca4d("grep/icase: avoid kwsset on literal non-ascii strings", 2016-06-25). Subsequent commits will change this behavior. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
