* (bug 1398) patch by Thue Janus Kristensen that modifies the behaviour of the

  'Go' button, if an IP address is entered the search engine first checks if an
  article by that name exists, otherwise it goes to the user contributions list
  of that search engine ( this would catch en.wp.org/wiki/127.0.0.1 ), also,
  entering a valid username with the current namespace-3 + : prefix will go to
  the users page, regardless of whether it contains any text or not.
