Log message:
        (handle_dollar, handle_at): Now takes int
        token_type, not braced_code code_kind.  All uses changed.
        (SC_PRE_CODE): New state, for scanning after a keyword that
        has (or usually has) an immediately-following braced code.
        (token_type): New local var, to keep track of which token type
        to return when scanning braced code.
        (<INITIAL>"%destructor", <INITIAL>"%lex-param",
        <INITIAL>"%parse-param", <INITIAL>"%printer,
        <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
        instead of returning a token type immediately.
        (<INITIAL>"{"): Set token type.
        (<SC_BRACED_CODE>"}"): Use it.
        (handle_action_dollar, handle_action_at): Now returns bool
        indicating success.  Fail if ! current_rule; this prevents a core dump.
        (handle_symbol_code_dollar, handle_symbol_code_at):
        Remove; merge body into caller.
        (handle_dollar, handle_at): Complain in invalid contexts.
