		98	Argument names also often indicate the type of a parameter. Here are
		99	some hints on what they mean:
		100
		101	$text
		102	Rxvt-unicodes special way of encoding text, where one "unicode"
		103	character always represents one screen cell. See row_t for a
		104	discussion of this format.
		105
		106	$string
		107	A perl text string, with an emphasis on text. It can store all
		108	unicode characters and is to be distinguished with text encoded in a
		109	specific encoding (often locale-specific) and binary data.
		110
		111	$octets
		112	Either binary data or - more common - a text string encoded in a
		113	locale-specific way.
		114
		115	Extension Objects
		116	Very perl extension is a perl class. A separate perl object is created
		117	for each terminal and each extension and passed as the first parameter
		118	to hooks. So extensions can use their $self object without having to
		119	think about other extensions, with the exception of methods and members
		120	that begin with an underscore character "_": these are reserved for
		121	internal use.
		122
		123	Although it isn't a "urxvt::term" object, you can call all methods of
		124	the "urxvt::term" class on this object.
		125
		126	It has the following methods and data members:
		127
		128	$urxvt_term = $self->{term}
		129	Returns the "urxvt::term" object associated with this instance of
		130	the extension. This member must not be changed in any way.
		131
		132	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		133	Dynamically enable the given hooks (named without the "on_" prefix)
		134	for this extension, replacing any previous hook. This is useful when
		135	you want to overwrite time-critical hooks only temporarily.
		136
		137	$self->disable ($hook_name[, $hook_name..])
		138	Dynamically disable the given hooks.

		221	on_add_lines $term, $string
		222	Called whenever text is about to be output, with the text as

		224	returning a true value and calling "$term->scr_add_lines" yourself.
		225	Please note that this might be very slow, however, as your hook is

		231
		232	on_line_update $term, $row
		233	Called whenever a line was updated or changed. Can be used to filter

		235	lines that are being shown will be filtered, and, due to performance
		236	reasons, not always immediately.

		238	The row number is always the topmost row of the line if the line

		240
		241	Please note that, if you change the line, then the hook might get
