// @name        Clean up ext links
// @namespace   http://elzevir.fr/
// @description Remove the annoying prefix sometimes added to external links.
//
//              Some popular blog platforms such as over-blog think it's
//              appropriate to prefix every external link with something like
//              http://blogname.domain.tld/ext to display a banner with their
//              name above the page.  This script cleans up the external links
//              to remove this annoying addition.
//
//              Currently supports only over-blog.
// @include     http://*.over-blog.com/*
// @require     http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js
// ==/UserScript==

// This is the list of things that will be removed from all links.
//
// Feel free to expand it; remember to add a matching @include line above.
// Please let me know about your additions, I'll include them in the script.
