BUG#11762933: MYSQLDUMP WILL SILENTLY SKIP THE `EVENT`

              TABLE DATA IF DUMPS MYSQL DATABA
Problem: If mysqldump is run without --events (or with --skip-events)
it will not dump the mysql.event table's data. This behaviour is inconsistent
with that of --routines option, which does not affect the dumping of
mysql.proc table. According to the Manual, --events (--skip-events) defines,
if the Event Scheduler events for the dumped databases should be included
in the mysqldump output and this has nothing to do with the mysql.event table
itself.
Solution: A warning has been added when mysqldump is used without --events 
(or with --skip-events) and a separate patch with the behavioral change 
will be prepared for 5.6/trunk.
