  do not set filter column here;
  (setModel): filter model is not a pointer, set filter column here;
  (filter_update): use wildcard instead of reg. exp., filter model no pointer;
  (filter_activate): filter model no pointer;
  (update_filter_history): remove an existing item of current one,
  insert current to first position and amke sure it stays the current item;
  (handle_model_changed): filter model is no pointer

* workspace-view.h: filter model is no pointer
