ChangeSet@stripped, 2006-08-31 07:27:34-07:00, igor@stripped +4 -0
  Fixed bug #16249: different results for a range with an without index 
  when a range condition use an invalid DATETIME constant.
  Now we do not use invalid DATETIME constants to form end keys for
  range intervals: range analysis just ignores predicates with such
  constants.
