propsed patch
When $wgAllowPageInfo=true and use the info action, if the specified page does not exists, the output is (as seen in the web browser) :
There is currently no text in this page, you can [[Special:Search/Main Page|search for this page title]] in other pages or [http://localhost/w/index.php?title=Main_Page&action=edit edit this page].
The variables are replaced ($wgParser->transformMsg() is used) but then the links are not replaced because $wgOut->addHTML() is used instead of $wgOut->addWikiText(). I prose also to put the text in <div class='noarticletext'> like the "normal" message (used in action=view).
