Since Redirects are shown in a different fashion in the "What links here" pages,
I think it would be good to show the template relations in the same manner.
For instance, there is a template {{foo}} and pages [[bar]], [[baz]] and [[bat]]
contain the template. Now, the template itself contains a link to, say,
[[quux]]. Therefore, the three aforementioned articles (ba*) contain the link
[[quux]]. In the "What links here" page for [[quux]], the result should be
treelike, resembling redirects:
The following pages link to here:
View (previous 50) (next 50) (20 | 50 | 100 | 250 | 500).
*[[quuxx]] (redirect page)
**[[Xyzzy]]
*[[Template:foo]] (template page)
**[[bar]]
**[[baz]]
**[[bat]]
*[[shme]]
