An experimental query-planner change that reduces the estimated number
5c8cd31 
of output rows for FROM clause terms that are restricted by a LIKE or
GLOB operator, based on the number of bytes in the pattern.  The idea is
that longer patterns will match fewer records and hence should reduce the
estimated output count.  The implementation is not workable as it stands
now.  This is just a crazy idea, saved for future reference.
