If only a few rows have changed, emit each as a separate row_changed event

2005-06-08  Not Zed  <NotZed@Ximian.com>

        * e-tree-selection-model.c (etsm_toggle_single_row)
        (etsm_select_single_row): If only a few rows have changed, emit
        each as a separate row_changed event rather than triggering a
        complete redraw of the whole window.
