code: @Override
      public void onMacroBlock(String macroName, WikiParameters params, String content)
      {
          getListener().onMacro(macroName, convertParameters(params), content, false);
      }
docs: A macro block was found and it's separated at least by one new line from the next block. If there's no new line
  with the next block then wikimodel calls
  {@link #onMacroInline(String, org.xwiki.rendering.wikimodel.WikiParameters, String)} instead.
  <p>
  In wikimodel block elements can be:
  <ul>
  <li>at the very beginning of the document (no "\n")</li>
  <li>just after at least one "\n"</li>
  </ul>
