The sequence ? \ LF reads in as -1.  This is because read_escape reads
LF as -1 for the convenience of string reading.  But ? should check,
and give an error

    case '?':
      {
	register Lisp_Object val;

	XSET (val, Lisp_Int, READCHAR);
	if (XFASTINT (val) == '\\')
	  XSETINT (val, read_escape (readcharfun));

	if (XFASTINT (val) == -1)
	   error ("Invalid escape character syntax");

	return val;
      }
