          "Dynamically added link-tag disables the use of change styles 
           dynamically"

        * khtml/html/html_headimpl.cpp:
        (WebCore::HTMLLinkElementImpl::process):
        - dynamically added link-tags for stylesheets were messing up the
          counting of pending stylesheets.  If a head link element 
          specifies a new stylesheet but the previously specified 
          stylesheet is still loading, tell the document that stylesheets 
          are loaded so that there are no remaining requests for it to be 
          loaded.
