Modified files:
	src            : scan-gram.l 

Log message:
	(code_start): Initialize it to scanner_cursor,
	not loc->end, since loc->end might contain garbage and this leads
	to undefined behavior on some platforms.
	(id_loc, token_start): Use (IF_LINTed) initial values that do not
	depend on *loc, so that the reader doesn't give the the false
	impression that *loc is initialized.
	(<INITIAL>"%%"): Do not bother setting code_start, since its value
	does not survive the return.
