Our docs on how to setup shorturls have been horrible for awhile. They just about all suggest /index.php?title=$1 based rewrite rules. Despite the fact that MediaWiki has REQUEST_URI based handling code to extract titles from shorturls itself. The result is that a lot of these wiki have bugs with titles like [[C++]] and [[A&B]].
I'd like to get a bunch of wiki users running on different shared hosts and using these rewrite-rule based short urls. If I could get some people to spare some time, I can fix up the rewrite rules used for configuration to work in a more elegant and stable way, and we can test and see how these rules function on different shared hosts.
Naturally I have no interest in pre-1.11 installs (1.11 is when the REQUEST_URI stuff was introduced).
...one of these days I suppose I'm also going to have to sort out the absolutely horrible nginx instructions too. ((actually if anyone is using nginx, I'd be happy to sort out your config too))
