83193d0133 The IN-early-out optimization: When doing a look-up on a multi-column index 
and an IN operator is used on a column other than the left-most column, then
if no rows match against the first IN value, check to make sure there exist
rows that match the columns to the right before continuing with the next IN
value.

advantage of this new capability.
