If an article has a space in its title, {{fullurl:{{FULLPAGENAME}}}} is smart
enough to convert the space to an _.  But it fails to correctly escape (, ), +,
%, and possibly other characters.

This causes the following two problems, and possibly others:

1) At a page with % in its title, {{fullurl:{{FULLPAGENAME}}}} produces an
invalid URL.  For example, if the page title is merely %, the URL is
http://en.wikipedia.org/wiki/%, instead of .../wiki/%25

2) See http://en.wikipedia.org/wiki/Ben-Hur_%281959_film%29  Click on one of the
footnote links (there's one at the beginning of the second paragraph of the
"Synopsis" section).  The link is to
http://en.wikipedia.org/wiki/Ben-Hur_(1959_film)#endnote_galleyslave  Since that
URL is different from the current page, it forces the web browser to reload the
same article, instead of simply jumping down to the footnote.


MediaWiki already has the ability to convert arbitrary strings to links.  For
example, it knows how to produce URLs for [[Ben-Hur (1959 film)]] and [[%]]. 
The {{fullurl}} code should simply use ''exactly the same routine'' that
MediaWiki uses everywhere else.
