        (pattern): New member multi_line for multi-line regexps.
        (filebuf): A global buffer containing the whole file as a string
        for multi-line regexp matching.
        (need_filebuf): Global flag raised if multi-line regexps used.
        (print_help): Document new regexp modifiers, remove references to
        obsolete option --ignore-case-regexp.
        (main): Do not set regexp syntax and translation table here.
        (main): Treat -c option as a backward compatibility hack.
        (main, find_entries): Init and free filebuf.

        (readline): Check for regex matching null string.
        (find_entries): Reorganisation.
