2ad07d96b6 Improved fix for ticket [ced41c7c7d6b4d36] that keeps skip-scan enabled, 
but avoids identifying a skip-scan as order-distinct (because it is not)
and thus forces a separate b-tree to implement the DISTINCT clause of a
query.  This undoes check-in [a871d69c6de65038] and substitutes a new fix.
