Documentation: invalid xhtml syntax

here's the offending code from line 116 (v 1.150):

    case 'search#noresults':
      return t('<p><ul>
<li>Check if your spelling is correct.</li>
<li>Remove quotes around phrases to match each word individually: <em>"blue smurf"</em> will match less than <em>blue smurf</em>.</li>
<li>Consider loosening your query with <em>OR</em>: <em>blue smurf</em> will match less than <em>blue OR smurf</em>.</li>
</ul></p>');

It looks like we could just remove the <p> and </p> tags and be okay.

Attached patch.

Committed to HEAD.
