      Fixed bug #25602. A query with DISTINCT in the select list to which · 59b9077c
      igor@olga.mysql.com authored
      the loose scan optimization for grouping queries was applied returned 
      a wrong result set when the query was used with the SQL_BIG_RESULT
      option.
      
      The SQL_BIG_RESULT option forces to use sorting algorithm for grouping
      queries instead of employing a suitable index. The current loose scan
      optimization is applied only for one table queries when the suitable
      index is covering. It does not make sense to use sort algorithm in this
      case. However the create_sort_index function does not take into account
      the possible choice of the loose scan to implement the DISTINCT operator
      which makes sorting unnecessary. Moreover the current implementation of
      the loose scan for queries with distinct assumes that sorting will
      never happen. Thus in this case create_sort_index should not call
      the function filesort.

      Occasionally mysqlbinlog --hexdump failed with error:
        ERROR 1064 (42000) at line ...: You have an error in your
        SQL syntax; check the manual that corresponds to your MySQL
        server version for the right syntax to use near
        'Query thread_id=... exec_time=... error_code=...
      
      When the length of hexadecimal dump of binlog header was
      divisible by 16, commentary sign '#' after header was lost.
      The Log_event::print_header function has been modified to always
      finish hexadecimal binlog header with "\n# ".
