    unknown authored
    - Make the range-et-al optimizer produce E(#table records after table 
                                               condition is applied),
    - Make the join optimizer use this value,
    - Add "filtered" column to EXPLAIN EXTENDED to show 
      fraction of records left after table condition is applied
    - Adjust test results, add comments
