Privileges of MySQL backup user for mysqldump

Some MySQL customers do not want to use the root user for mysqldump backups. For this user you have to grant the following minimal MySQL privileges:

mysqldump --single-transaction (InnoDB)

CREATE USER 'backup'@'localhost' IDENTIFIED BY 'secret';
GRANT SELECT, SHOW VIEW, RELOAD, REPLICATION CLIENT, EVENT, TRIGGER ON *.* TO 'backup'@'localhost';

mysqldump --lock-all-tables (MyISAM)

GRANT LOCK TABLES ON *.* TO 'backup'@'localhost';

If we missed a privilege please let us know.
