         *      out automatically.
         *   2) It automatically adds the usual classes for various types of link
         *      targets: "new" for red links, "stub" for short articles, etc.
         *   3) It escapes all attribute values safely so there's no risk of XSS.
         *   4) It provides a default tooltip if the target is a Title (the page
         *      name of the target).
         * link() replaces the old functions in the makeLink() family.
         *
         * @param $target        Title  Can currently only be a Title, but this may
         *   change to support Images, literal URLs, etc.
         * @param $text          string The HTML contents of the <a> element, i.e.,
         *   the link text.  This is raw HTML and will not be escaped.  If null,
         *   defaults to the prefixed text of the Title; or if the Title is just a
         *   fragment, the contents of the fragment.
         * @param $customAttribs array  A key => value array of extra HTML attri-
         *   butes, such as title and class.  (href is ignored.)  Classes will be
         *   merged with the default classes, while other attributes will replace
         *   default attributes.  All passed attribute values will be HTML-escaped.
         *   A false attribute value means to suppress that attribute.
         * @param $query         array  The query string to append to the URL
         *   you're linking to, in key => value array form.  Query keys and values
         *   will be URL-encoded.
         * @param $options       mixed  String or array of strings:
         *     'known': Page is known to exist, so don't check if it does.
         *     'broken': Page is known not to exist, so don't check if it does.
         *     'noclasses': Don't add any classes automatically (includes "new",
         *       "stub", "mw-redirect", "extiw").  Only use the class attribute
         *       provided, if any, so you get a simple blue link with no funny i-
         *       cons.
         *     'forcearticlepath': Use the article path always, even with a querystring.
         *       Has compatibility issues on some setups, so avoid wherever possible.
