t/README: test_must_fail is for testing Git
When a test wants to make sure there is no <string> in an output file, we should just say "! grep string output". "test_must_fail" is there only to test Git command and catch unusual deaths we know about (e.g. segv) as an error, not as an expected failure. "test_must_fail grep string output" is unnecessary, as we are not making sure the system binaries do not dump core or anything like that. Signed-off-by: Junio C Hamano <gitster@pobox.com>
