SVG use fail for <object> data

Chromium issue: http://code.google.com/p/chromium/issues/detail?id=148786

When the SVG document is embedded as inline <object> data, the use element doesn't seem work. Same document embedded as inline <img> data works fine (see attached test).

The problem seems to be that href's are always considered external when embedding via <object> data.

SVGURIReference::isExternalURIReference():

        // If the URI matches our documents URL, early exit, we're dealing with a local reference.
        ASSERT(document);
        KURL url = document->completeURL(uri);
        if (equalIgnoringFragmentIdentifier(url, document->url()))
            return false;

        // If the URI doesn't contain a base string, just see if it starts with a fragment-identifier.
        return uri.find('#') != notFound;

For <object> data-embedded SVGs, the document URL is set to the actual 'data' attribute value (unlike <img>'s). So the test above falls through and hits the last return.... which is odd as it doesn't seem to do what the comment says at all: shouldn't we just check if the first character matches '#'?

I'll post a patch shortly.
