MFC r322368, r322371:
fnmatch(3): improve POSIX conformance. In a recent interpretation[1], "\\" shall return a non-zero value (indicating either no match or an error). The fix involves a change over r254091 and now the behavior matches the Sun/IBM/HP closed source implementations and also likely musl libc.
