Wikimedia Bugzilla is closed!

Not a major issue, but the internal wiki links on the "no such article" page
come out malformed if there are unexpected characters in the page title
(especially '' and ''').

An example is:
http://en.wikipedia.org/wiki/%27%27%27%27%27

In this example, for me the rendered HTML output shows the "[[" and "]]" parts
of the wiki links, rather an rendering them as HTML links, such as this:
==============================
# [[Special:Search/|Search for "''''"]] in existing articles.*
[[Wiktionary:|Look for "''''"]] in Wiktionary, our sister dictionary project.
# [[Commons:|Look for '''']] in the Wikimedia Commons, our repository for free
images, music, sound, and video.
# [[Special:Whatlinkshere/|Look for pages within Wikipedia linking to this
article]].
