Summary: Segfault for debug scanners

Initial Comment:
In debug mode re2c generates code like this:
	YYDEBUG(0, *YYCURSOR);
	if ((YYLIMIT - YYCURSOR) < 11) YYFILL(11);

However before the scanner was filled, "cursor" will be NULL. (At least for the examples.)

I assume YYCURSOR should be filled before trying to access it. I.e. YYDEBUG after YYFILL.
