  fix for bug #16426, post fixes

  sql/sp_head.cc
    1.209 06/03/01 03:49:21 andrey@lmy004. +2 -2
    this was an error which passed code review. thd->enable_slow_log could be
    changed and it should not be relied

  mysql-test/t/events_slow_query.test
    1.2 06/03/01 03:49:21 andrey@lmy004. +4 -2
    create different event because the executor is buggy and won't catch the difference if
    the memory address does not change (will be reported as bug separately)

  mysql-test/r/events_slow_query.result
    1.2 06/03/01 03:49:21 andrey@lmy004. +6 -2
