            Saving of command-line history to file in
            mysql client. By Tommy Larsen
            <tommy@mix.hive.no>.
          
            Fixed problem with empty lines that were ignored in
            mysql.cc.
          
Save the pid of the signal handler thread in the pid file instead of the pid of the main thread.
            Added patch by <tommy@valley.ne.jp> to support
            Japanese characters SJIS and UJIS.
          
            Changed safe_mysqld to redirect startup
            messages to 'hostname'.err instead of
            'hostname'.log to reclaim file space on
            mysqladmin refresh.
          
            ENUM always had the first entry as
            default value.

            update log.
          
            sql_acc() now closes the
            mysql grant tables after a reload to save
            table space and memory.
          
            Changed LOAD DATA to use less memory with
            tables and BLOB columns.
          
Sorting on a function which made a division / 0 produced a wrong set in some cases.
            Fixed SELECT problem with

            czech character set.
          
            Fixed problem in isamchk; it couldn't
            repair a packed table in a very unusual case.
          
            SELECT statements with
            & or | (bit
            functions) failed on columns with NULL
            values.
          
When comparing a field = field, where one of the fields was a part key, only the length of the part key was compared.
