nit: unrelated change?

I can remove this part of the change if you like.  It's related in the sense
that multipart was the primary client of FrameLoader::setReplacing.  This code
is now the only remaining client.  If we can remove it, we can remove another
chunk of code in FrameLoader.

         frame()->loader()->setReplacing();
     }
 }
 
 void WebFrameImpl::loadHTMLString(const WebData& data, const WebURL& baseURL, const WebURL& unreachableURL, bool replace)
 {
     ASSERT(frame());
     loadData(data, WebString::fromUTF8("text/html"), WebString::fromUTF8("UTF-8"), baseURL, unreachableURL, replace);
 }
