Subject: [PATCH] * Added a new associative array ($wgSpecialPageRedirects)
 that holds   Specialpages to redirect from and to as keys and values
 respectively,   executePath() now uses it to check if it should redirect the
 request for a   specialpage to another location.   This removes the need for
 keeping stub redirects around in case we merge or   rename SpecialPages.
