Log message:
        * tests/options.at (debug-flags): Update to reflect new message.
        (deprecated options, prepend-include, help and version): New
        tests.
        * tests/testsuite.at (AT_CHECK_M4): Avoid hanging testsuite if
        test omits an input file name.
        * src/main.c (long_options, main): Add -B/--prepend-include.
        (usage): Document it.
        (main): `m4 --help --version' now displays help, not version.
        * ltdl/m4/gnulib-cache.m4: Augment with gnulib-tool --import
        dirname filenamecat.
        * m4/m4module.h (m4_add_include_directory): Add parameter.
        * m4/m4private.h (m4__include_init): New prototype.
        * m4/m4.c (m4_create): Put `.' on path before options are
        collected.
        * m4/path.c (includes): Assume C89.  Use gnulib for file name
        management.
        (m4__include_init): New function.
        (search_path_add): Allow prepending.
        (m4_add_include_directory, search_path_env_init): Adjust callers.
        (m4_path_search): Relative names now invoke path search, since
        `.' might not be first.
        * doc/m4.texinfo (Invoking m4, Search Path): Document new option.
