		213	information is up-to-date when this happens. For interoperability, the

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

		228	output.
		229
		230	=item on_line_update $term, $row
		231
		232	Called whenever a line was updated or changed. Can be used to filter
		233	screen output (e.g. underline urls or other useless stuff). Only lines
		234	that are being shown will be filtered, and, due to performance reasons,
		235	not always immediately.
		236
		237	The row number is always the topmost row of the line if the line spans
		238	multiple rows.
		239
		240	Please note that, if you change the line, then the hook might get called
		241	later with the already-modified line (e.g. if unrelated parts change), so
