* bigram coding by a further 20-25%.
*
* The codes are:
*
*
* 0-28 likeliest differential counts + offset to make nonnegative
* 30 switch code for out-of-range count to follow in next word
* 128-255 bigram codes (128 most common, as determined by 'updatedb')
* 32-127 single character (printable) ascii residue (ie, literal)
*
*
* A novel two-tiered string search technique is employed:
*
*
* First, a metacharacter-free subpattern and partial pathname is matched
* BACKWARDS to avoid full expansion of the pathname list. The time savings
* is 40-50% over forward matching, which cannot efficiently handle
* overlapped search patterns and compressed path residue.
*
*
* Then, the actual shell glob-style regular expression (if in this form) is
* matched against the candidate pathnames using the slower routines provided
* in the standard 'find'.
