gtk2/gtk/gtkfilechooserdefault.c
Jan Arne Petersen 77cbf47adf add REMOVABLE column to the shortcuts_model. 
2004-01-07  Jan Arne Petersen  <jpetersen@uni-bonn.de>

        * gtk/gtkfilechooserdefault.c: (shortcuts_insert_path),
        (shortcuts_append_home), (shortcuts_append_desktop),
        (shortcuts_append_paths), (shortcuts_add_volumes),
        (shortcuts_append_bookmarks), (create_shortcuts_model),
        (gtk_file_chooser_default_add_shortcut_folder): add REMOVABLE column
        to the shortcuts_model.

        (remove_bookmark_button_clicked_cb),
        (bookmarks_check_remove_sensitivity): use REMOVABLE column to check if
        bookmarks can be removed. Fixes #129873
