• Redirects with special pages don't work;

I'll take a look at that--that's a special piece of code in Article.php.

• Somebody commented out the rewrite rules I added that kept

existing links to the wiki intact. I put them back.

That was me; I was just debugging something and I wasn't sure what they did so I commented them out to make sure they weren't causing my problem. But if they work OK now, they shoulud certainly be left in.
