		43
		44	Intelligent selection. This extension tries to be more intelligent when
		45	the user extends selections (double-click). Right now, it tries to select
		46	urls and complete shell-quoted arguments, which is very convenient, too,
		47	if your F<ls> supports C<--quoting-style=shell>.

		210
		211	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		212	operating system command) is processed. Cursor position and other state
		213	information is up-to-date when this happens. For interoperability, the
		214	string should start with the extension name and a colon, to distinguish
		215	it from commands for other extensions, and this might be enforced in the

		217
		218	Be careful not ever to trust (in a security sense) the data you receive,

		222	=item on_add_lines $term, $string
		223
		224	Called whenever text is about to be output, with the text as argument. You
		225	can filter/change and output the text yourself by returning a true value
		226	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		227	might be very slow, however, as your hook is called for B<all> text being
		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

		918	this many lines into the scrollback buffer.
		919
		920	=item $term->want_refresh
		921
		922	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		923	compare the on-screen display with its stored representation. If they
		924	differ, it redraws the differences.
		925
		926	Used after changing terminal contents to display them.
		927
		928	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		929
		930	Returns the text of the entire row with number C<$row_number>. Row C<0>
		931	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		932	terminal line. The scrollback buffer starts at line C<-1> and extends to
		933	line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
		934	is requested.
		935
		936	If C<$new_text> is specified, it will replace characters in the current
		937	line, starting at column C<$start_col> (default C<0>), which is useful
		938	to replace only parts of a line. The font index in the rendition will
		939	automatically be updated.
		940
		941	C<$text> is in a special encoding: tabs and wide characters that use more
		942	than one cell when displayed are padded with urxvt::NOCHAR characters
		943	(C<chr 65535>). Characters with combining characters and other characters
		944	that do not fit into the normal tetx encoding will be replaced with
		945	characters in the private use area.
		946
		947	You have to obey this encoding when changing text. The advantage is
		948	that C<substr> and similar functions work on screen cells and not on
		949	characters.
		950
		951	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		952	can be used to convert normal strings into this encoding and vice versa.
		953
		954	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		955
		956	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		957	bitsets. Rendition bitsets contain information about colour, font, font
		958	styles and similar information. See also C<< $term->ROW_t >>.
		959
		960	When setting rendition, the font mask will be ignored.
		961
		962	See the section on RENDITION, above.
		963
		964	=item $length = $term->ROW_l ($row_number[, $new_length])
		965
		966	Returns the number of screen cells that are in use ("the line
		967	length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
		968	line is joined with the following one.
		969
		970	=item $bool = $term->is_longer ($row_number)
		971
		972	Returns true if the row is part of a multiple-row logical "line" (i.e.
		973	joined with the following row), which means all characters are in use
		974	and it is continued on the next row (and possibly a continuation of the
		975	previous row(s)).
		976
		977	=item $line = $term->line ($row_number)
		978
		979	Create and return a new C<urxvt::line> object that stores information
		980	about the logical line that row C<$row_number> is part of. It supports the
		981	following methods:
		982
		983	=over 4
		984
		985	=item $text = $line->t ([$new_text])
		986
		987	Returns or replaces the full text of the line, similar to C<ROW_t>
		988
		989	=item $rend = $line->r ([$new_rend])
		990
		991	Returns or replaces the full rendition array of the line, similar to C<ROW_r>
		992
		993	=item $length = $line->l
		994
		995	Returns the length of the line in cells, similar to C<ROW_l>.
		996
		997	=item $rownum = $line->beg
		998
		999	=item $rownum = $line->end
		1000
		1001	Return the row number of the first/last row of the line, respectively.
		1002
		1003	=item $offset = $line->offset_of ($row, $col)
		1004
		1005	Returns the character offset of the given row\|col pair within the logical
		1006	line.
		1007
		1008	=item ($row, $col) = $line->coord_of ($offset)
		1009
		1010	Translates a string offset into terminal coordinates again.
