* lib/dfa.c (lex): Pay no attention to RE_LIMITED_OPS when
deciding how to parse '\n', since regcomp.c doesn’t.

        dfa: new option DFA_STRAY_BACKSLASH_WARN
        This is for grep, which wants to warn about stray backslashes that
        lead to unspecified behavior.  For example, "grep -oi '\a'"
