mysqldump ignore-table doesn't ignore mysql.slow_log or mysql.general_log

When doing a full DB dump with mysqldump some tables are dumped regardles of their appearance in --ignore-table.

/usr/bin/mysqldump --defaults-file=/etc/mysql/mydump.cnf -u<user> -p<password> --add-locks --extended-insert --add-locks --add-drop-database --add-drop-table --single-transaction --routines --triggers --all-databases --all-tablespaces --allow-keywords --complete-insert --create-options --events --dump-date>/root/db.sql

cat /etc/mysql/mydump.cnf

[mysqldump]

ignore-table=mysql.general_log

ignore-table=mysql.slow_log

Still contains the two tables, other mysql.* tables can be ignored, worse in some cases it also contains the drop statement which causes an import to fail! (when dumping the whole server the export includes "/!40000 DROP DATABASE IF EXISTS `mysql`/;" which breaks if we attempt to import it).
