 - Added workaround for bug #100342 in Expect.pm when parsing ouput of
   Linux commands.
 - Added new config option "keep_history".
   This option determines, after how many days old history files are removed.
   The value must be >= 30. Default value is 365.
 - Script "delete-old-policies" now also removes old files
   in "historydir" and "statusdir".
