- Detect if a table has field of type MYSQL_TYPE_VAR_STRING while running "CHECK TABLE t FOR UPGRADE" and indicate it need to be fixed with "REPAIR TABLE t". - When running a "REPAIR TABLE t" or "ALTER TABLE t FORCE" on the above table, install a special copy function to trim off the trailing spaces which we safely can say that the pre 5.0 mysqld didn't put there.
