Our docs on how to setup shorturls have been horrible
for awhile.
They just about all suggest /index.php?title=$1 based rewrite rules.
Despite the fact that MediaWiki has REQUEST_URI based handling code to
extract titles from shorturls itself.
The result is that a lot of these wiki have bugs with titles like
[[C++]] and [[A&B]].
They work fine with QSA flag, which most servers should support by now.
RewriteRule ^wiki/?(.*)$ /w/index.php?title=$1 [L,QSA]
