Modified files:
	src            : scan-gram.l 

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.
