There is no link/button that will allow editing of the pdf tag wiki. Improve this tag wiki pink just redirects back to the tag wiki page.
What is going on?
(Note DanielBeck also has this problem, so it is not just a suggested editing issue)
Update: Even after Random edited the wiki he problem is not resolved
The pdf tag wiki was deleted at some point and any attempts to reach the main edit page would redirect back to its /info page, even for moderators.
How was it deleted? There was a hole in our permission checks - moderators were allowed to pretty much delete anything, including tag wikis (although, this is not exposed in the UI currently).
The gates have been barred and all wikis should now be editable again (based on privileges).
http://superuser.com/edit-tag-wiki/553 sends an HTTP 302 Found reply to redirect to the tag wiki page /tags/pdf/info. I don't think there's anything we can do to analyze this further.

With full privileges, the button to the edit page is identical to other tag wikis', no difference there:
<div class="post-menu"><form method='get' action='#' class='form-submit'><input type='button' value='Edit Tag Wiki' onclick="window.location.href='/edit-tag-wiki/553'"/></form><a href="/posts/247236/revisions">history</a><span class="lsep">|</span><a href='#' id='show-wiki-excerpt'>show excerpt</a><span class="lsep">|</span><a href="/posts/247237/revisions">excerpt history</a></div> <br class="cbt">

The PDF tag wiki editing page on SO can be reached without problems.
Since posting analysis in the comments is difficult, I declare this community wiki to be used for sharing our findings!
<div class="post-menu">
<form class="form-submit" action="#" method="get">

value="Edit Tag Wiki">

The markup for the Edit Tag Wiki button is completely missing and the excerpt history link (https://superuser.com/posts/247237/revisions) is broken.
When examining the latest history source, there is an extra newline at the end of the post (compared to the 'normal' tag wiki above). Could this be causing the bug? Can someone with tag wiki edit privileges try replicating this on a different tag?
http://superuser.com/edit-tag-wiki/553) doesn't work. But it is working on other tags, as expected. How strange :/
