drush civicrm-sql-dump fails to dump stored function

I just discovered that mysqldump needs the --routines switch in order to include Mysql stored functions in the dump file. So I tried drush civicrm-sql-dump to see if it would include this switch and I discovered that it didn't. I made dump with it and did not see any function definition included. Restoring with an incomplete dump file will result in a broken CiviCRM.

Please correct the drush functions and please highlight the need for this switch in documentation
