 132          *      out automatically.
 133          *   2) It automatically adds the usual classes for various types of link
 134          *      targets: "new" for red links, "stub" for short articles, etc.
 135          *   3) It escapes all attribute values safely so there's no risk of XSS.
 136          *   4) It provides a default tooltip if the target is a Title (the page
 137          *      name of the target).
 138          * link() replaces the old functions in the makeLink() family.

 141          *   change to support Images, literal URLs, etc.
 142          * @param $text          string The HTML contents of the <a> element, i.e.,
 143          *   the link text.  This is raw HTML and will not be escaped.  If null,
 144          *   defaults to the prefixed text of the Title; or if the Title is just a
 145          *   fragment, the contents of the fragment.
 146          * @param $customAttribs array  A key => value array of extra HTML attri-
 147          *   butes, such as title and class.  (href is ignored.)  Classes will be
 148          *   merged with the default classes, while other attributes will replace
 149          *   default attributes.  All passed attribute values will be HTML-escaped.
 150          *   A false attribute value means to suppress that attribute.
 151          * @param $query         array  The query string to append to the URL
 152          *   you're linking to, in key => value array form.  Query keys and values
 153          *   will be URL-encoded.

 155          *     'known': Page is known to exist, so don't check if it does.
 156          *     'broken': Page is known not to exist, so don't check if it does.

 158          *       "stub", "mw-redirect", "extiw").  Only use the class attribute
 159          *       provided, if any, so you get a simple blue link with no funny i-
 160          *       cons.
 161          *     'forcearticlepath': Use the article path always, even with a querystring.
