Repairs InnoDB tables after upgrade from MySQL 5.0 to MySQL 5.1
or from 4.1 to 5.0.
Only will run if you are on MySQL 5.1 or MySQL 5.0, set
--anyversion if you want to run this on a different version.
NOTE: this will rebuild each table and may not correct serious
corruptions. This is designed more as an upgrade task then
a real repair.
