Add missing ]] to terminate CDATA. Missing brackets are causing
the man page to contain:
               ></programlisting>

                     <para>And here are the same errors with
                     <option>--read-var-info=yes</option>:</para>

               <programlisting><![CDATA[

Rather than the nicely formatted 'And here ...' paragraph.
