		221	and calling C<< $term->scr_add_lines >> yourself. Please note that this

		225	=item on_line_update $term, $row
		226
		227	Called whenever a line was updated or changed. Can be used to filter

		229	that are being shown will be filtered, and, due to performance reasons,
		230	not always immediately.
