Description of problem:
This problem applies to programlistings with callouts.
<programlisingco> is a parent tag for applying callouts to a progamlisting. If the programlisting contains any empty lines with no data, Publican will fail when building HTML.

Example:
            <programlistingco role="XML">
                <areaspec>
                    <area id="subclass1" coords="2 55"/>
                    <area id="subclass2" coords="3 55"/>
                    <area id="subclass3" coords="4 55"/>
                    <area id="subclass4" coords="5 55"/>
                </areaspec>
                <programlisting role="XML"><![CDATA[<subclass
        name="X"
        discriminator-value="x"
        proxy="x"
        lazy="x"
        dynamic-update="x"
        dynamic-insert="x"
        entity-name="x"

        <property .... />
        .....
</subclass>]]></programlisting>
