(nautilus_tree_view_drag_motion): cleanup, make it call
tree_view_drag_destroy_real
(nautilus_tree_view_drag_drop): spaces.
(nautilus_tree_view_drag_data_received): cleanup: make it call
tree_view_drag_destroy.
(nautilus_dump_info): cleanup.
(expand_time_callback): cleanup.
(nautilus_tree_view_expand_maybe_later): cleanup
(nautilus_tree_view_collapse_all): cleanup.
