-/* Core algorithm.
-
-   For each 32-byte hunk we calculate a 64-bit syndrome value, with
-   two bits per byte (LSB is always in bits 0 and 1, for both big
-   and little-endian systems).  For each tuple, bit 0 is set iff
-   the relevant byte matched the requested character; bit 1 is set
-   iff the relevant byte matched the NUL end of string (we trigger
-   off bit0 for the special case of looking for NUL).  Since the bits
-   in the syndrome reflect exactly the order in which things occur
-   in the original string a count_trailing_zeros() operation will
-   identify exactly which byte is causing the termination, and why.  */
