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

		224
		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.

		234
		235	Please note that, if you change the line, then the hook might get called
		236	later with the already-modified line (e.g. if unrelated parts change), so
