		94	Argument names also often indicate the type of a parameter. Here are

		96
		97	$text
		98	Rxvt-unicodes special way of encoding text, where one "unicode"
		99	character always represents one screen cell. See row_t for a
		100	discussion of this format.
		101
		102	$string
		103	A perl text string, with an emphasis on text. It can store all
		104	unicode characters and is to be distinguished with text encoded in a
		105	specific encoding (often locale-specific) and binary data.
		106
		107	$octets
		108	Either binary data or - more common - a text string encoded in a
		109	locale-specific way.
		110
		111	Extension Objects
		112	Very perl extension is a perl class. A separate perl object is created
		113	for each terminal and each extension and passed as the first parameter
		114	to hooks. So extensions can use their $self object without having to
		115	think about other extensions, with the exception of methods and members
		116	that begin with an underscore character "_": these are reserved for
		117	internal use.
		118
		119	Although it isn't a "urxvt::term" object, you can call all methods of
		120	the "urxvt::term" class on this object.
		121
		122	It has the following methods and data members:
		123
		124	$urxvt_term = $self->{term}
		125	Returns the "urxvt::term" object associated with this instance of
		126	the extension. This member must not be changed in any way.
		127
		128	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		129	Dynamically enable the given hooks (named without the "on_" prefix)
		130	for this extension, replacing any previous hook. This is useful when
		131	you want to overwrite time-critical hooks only temporarily.
		132
		133	$self->disable ($hook_name[, $hook_name..])
		134	Dynamically disable the given hooks.

127	output.	207	operating system command) is processed. Cursor position and other
		208	state information is up-to-date when this happens. For
		209	interoperability, the string should start with the extension name
		210	and a colon, to distinguish it from commands for other extensions,
		211	and this might be enforced in the future.
		212
		213	Be careful not ever to trust (in a security sense) the data you
		214	receive, as its source can not easily be controleld (e-mail content,
		215	messages from other users on the same system etc.).
		216
		217	on_add_lines $term, $string
		218	Called whenever text is about to be output, with the text as
		219	argument. You can filter/change and output the text yourself by
		220	returning a true value and calling "$term->scr_add_lines" yourself.
		221	Please note that this might be very slow, however, as your hook is
		222	called for all text being output.
		223
		224	on_tt_write $term, $octets
		225	Called whenever some data is written to the tty/pty and can be used
		226	to suppress or filter tty input.
		227
		228	on_line_update $term, $row
		229	Called whenever a line was updated or changed. Can be used to filter
		230	screen output (e.g. underline urls or other useless stuff). Only
		231	lines that are being shown will be filtered, and, due to performance
		232	reasons, not always immediately.
		233
		234	The row number is always the topmost row of the line if the line
		235	spans multiple rows.
		236
		237	Please note that, if you change the line, then the hook might get
		238	called later with the already-modified line (e.g. if unrelated parts
		239	change), so you cannot just toggle rendition bits, but only set
		240	them.
