	Inputs:

	=back

	Takes the text and creates a link to the $text that honors
	the value of 'new window' if clicked on, but uses a real
	'href' so middle and right clicks still work.

	$target and $text are assumed to be already correctly escaped; i.e., it
	can be dumped out directly into the output stream as-is.
