Fix double redirects



A redirect is a special page that automatically causes the text of another page to be displayed in its place. A redirect that points to another redirect is called a double redirect. These pages are undesirable, since Wikipedia's MediaWiki software will not follow the second redirect, in order to prevent infinite loops. A self-redirect is an article that redirects to itself. These situations create slow, unpleasant experiences for the reader, waste server resources, and make the navigational structure of the site confusing.
