+	   to find out if any byte in xword could be zero. This is fast, but
+	   also gives false alarm for any byte in range 0x81-0xff. It does
+	   not matter for correctness, as if this test tells us there could
+	   be some zero byte, we check it byte by byte, but if bytes with
+	   high bits set are common in the strings, then this will give poor
+	   performance. You can #define EIGHTBIT_NOT_RARE and the algorithm
+	   will use one tick slower, but more precise test
+	   ((xword - 0x0101010101010101) & (~xword) & 0x8080808080808080),
+	   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).
+	   It is yet to be measured, what is the correct default for glibc
+	   in these days for an average user.
