Missing parameter in GtkTreeView function

[Jeff Franks <jcf tpg com au>]

Hi,

I was wondering why the new GtkTreeViewSearchEqualFunc in gtktreeview.h 
doesn't have a user_data field.
typedef gboolean (*GtkTreeViewSearchEqualFunc) (GtkTreeModel  *model,
                                                                       
              gint                     column,
                                                                       
              gchar                  *key,
                                                                        
             GtkTreeIter       *iter);
There is a search_user_data member in GtkTreeViewPrivate that gets set 
from 'gtk_tree_view_set_search_equal_func'
void  gtk_tree_view_set_search_equal_func (GtkTreeView *tree_view,
                           GtkTreeViewSearchEqualFunc  search_compare_func,
                           gpointer                                    
  search_data,
                           GtkDestroyNotify                       
search_destroy);
Is this an oversight? The other function signatures declared in 
gtktreeview.h all have user data fields.
Jeff.
