Drupal feed icon (and URL) has been changed

I believe the following would make the block (function syndication_block) more 4.7ish:

      if ($pagetype == 'blog') {
        $userid = arg(1);
        $linkurl = is_numeric($userid) ? "blog/$userid/feed" : 'blog/feed';
      } else {
        $linkurl = 'rss.xml';
      }
      $block['content'] = theme('feed_icon', url($linkurl));

Sorry, no patch this time. I hope you get the idea though.
