The mysql client uses the default character set on reconnect.  The default character set is now controled by the client charset command while the client is running.  The charset command now also issues a SET NAMES command to the server to make sure that the client's charset settings are in sync with the server's.

mysql-test/r/mysql.result:
  Corrected results for new behaviour.
