Redirect-related bugfixes/features:
- (bug 11644) Add $wgMaxRedirects variable to control how many redirects are recursed through until the "destination" page is reached.
- update redirect page UI to show each step down to the destination page
- rdfrom text still links to original page visited
- pages still show up in DoubleRedirects
- setting to 1 (default) is current behavior of only going 1 step down. Setting to 0 disables automatic redirects.
- arrow image needs to be smoothed, couldn't figure out how to do it myself while keeping the image in indexed mode
- (bug 10569) Redirects to Special:Mypage and Special:Mytalk are no longer allowed to prevent redirect loops
- can be re-enabled by changing the $wgInvalidRedirectTargets array
