    Description

      In all attempts, I was never able to get any other "plan" than this for SHOW EXPLAIN in the slow log:

      # Time: 131009 20:35:29
      # User@Host: root[root] @ localhost [127.0.0.1]
      # Thread_id: 6  Schema: test  QC_hit: No
      # Query_time: 0.002340  Lock_time: 0.000849  Rows_sent: 1  Rows_examined: 1
      #
      #  id   select_type     table   type    possible_keys   key     key_len ref     rows    Extra
      #  1    SIMPLE  EXPLAIN ALL     NULL    NULL    NULL    NULL    NULL    
      #
      SET timestamp=1381336529;
      show explain for 4;

      If it's really going to be always the same, maybe it doesn't make sense to print it there at all.
