Documentation: Sorting example does not work

[Thilo Wischmeyer]

On the page http://assemble.io/docs/Collections.html , the example code for sorting does not work:

<ul>
    {{#withSort pages data.date}}
        <li>{{data.title}}</li>
    {{/withSort}}
</ul>

The quotation marks around data.date are missing. It should be:

<ul>
    {{#withSort pages "data.date"}}
        <li>{{data.title}}</li>
    {{/withSort}}
</ul>
