cplus-dem.c (standard_symbol_characters): Renamed from standard_symbol_alphabet.

        * cplus-dem.c (standard_symbol_characters): Renamed from
        standard_symbol_alphabet.  No longer modify TABLE.
        (hp_symbol_characters): Renamed from hp_symbol_alphabet.  No longer
        modify TABLE.
        (main): Corresponding changes.  Use strchr to determine if a
        character is valid.
