        The following changes (and some of 2002-08-20 changes of mine) are
        for handling syntax, category, and case conversion for unibyte
        characters by converting them to multibyte on the fly.  With these
        changes, we don't have to setup syntax and case tables for unibyte
        characters in each language environment.

        * abbrev.c (Fexpand_abbrev): Convert a unibyte character to
        multibyte if necessary.

        macro.
        (multibyte_char_to_unibyte): If C is an eight-bit character,
        convert it to the corresponding byte value.

        * charset.c (Fset_unibyte_charset): If the dimension of CHARSET is
        not 1, singals an error.  Update the elements of
        unibyte_to_multibyte_table.
        (init_charset_once): Initialize unibyte_to_multibyte_table.
        (syms_of_charset): Define the charset `iso-8859-1'.

        * casefiddle.c (casify_object): Fix previous change.

        * cmds.c (internal_self_insert): In a multibyte buffer, insert C
        as is without converting it to unibyte.  In a unibyte buffer,
        convert C to multibyte before checking the syntax.

        non-emacs case.
        (PATFETCH): Convert an eight-bit char to multibyte.
        (HANDLE_UNIBYTE_RANGE): New macro.
        (regex_compile): Setup the compiled pattern for multibyte chars
        even if the given regex string is unibyte.  Use PATFETCH_RAW
        instead of PATFETCH in many places.  To handle `charset'
        specification of unibyte, call HANDLE_UNIBYTE_RANGE.   Use bitmap
        only for ASCII chars.
        (analyse_first) <exactn>: Simplified because the compiled pattern
        is multibyte.

        (re_compile_fastmap) [emacs]: Call analyse_first with the arg
        multibyte always 1.
        (re_search_2) In emacs, set the locale variable multibyte to 1,
        otherwise to 0.  New local variable target_multibyte.  Check it
        to decide the multibyteness of STR1 and STR2.  If
        target_multibyte is zero, convert unibyte chars to multibyte
        before translating and checking fastmap.
        (TARGET_CHAR_AND_LENGTH): New macro.
        (re_match_2_internal): In emacs, set the locale variable multibyte
        to 1, otherwise to 0.  New local variable target_multibyte.  Check
        it to decide the multibyteness of STR1 and STR2.  Use
        TARGET_CHAR_AND_LENGTH to fetch a character from D.
        <charset, charset_not>: If multibyte is nonzero, check fastmap
        only for ASCII chars.   Call bcmp_translate with
        target_multibyte, not with multibyte.
        <begline>: Declare the local variable C as `unsigned'.
        (bcmp_translate): Change the last arg name to target_multibyte.

        * search.c (compile_pattern_1): Don't adjust the multibyteness of
        the regexp pattern and the matching target.  Set cp->buf.multibyte
        to the multibyteness of the regexp pattern.  Set
        cp->but.target_multibyte to the multibyteness of the matching
        target.
        (wordify): Use FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE instead of
        FETCH_STRING_CHAR_ADVANCE.
        (Freplace_match): Convert unibyte chars to multibyte.

        * syntax.c (char_quoted): Use FETCH_CHAR_AS_MULTIBYTE to convert
        unibyte chars to multibyte.

        handling syntaxes is moved to skip_syntaxes.  Callers changed.
        Fix the case that the multibyteness of STRING and the current
        buffer doesn't match.
        (skip_syntaxes): New function.
        (SYNTAX_WITH_MULTIBYTE_CHECK): Check C by ASCII_CHAR_P, not by
        SINGLE_BYTE_CHAR_P.
        (Fforward_comment): Use FETCH_CHAR_AS_MULTIBYTE to convert unibyte
        chars to multibyte.
        (scan_lists): Likewise.
