+	   also gives false alarm for any byte in range 0x81-0xff. It does

+	   high bits set are common in the strings, then this will give poor

+	   ((xword - 0x01010101) & (~xword) & 0x80808080),
+	   which does not give any false alarms (but if some bits are set,
+	   one cannot assume from it which bytes are zero and which are not).
