What does this do in javascript?
<p>I came across the function below in one of the SharePoint system javascript files.</p>

<pre><code>function RTE_InsertImage(strBaseElementID)
{ULS1Lu:;
   //A bunch of javascript
}
</code></pre>

<p>I have never seen something like <code>ULS1Lu:;</code> in any of the javascript code I have worked with before.  Does anyone know what this is doing?</p>

<p>Sorry the weak title on the question.  I wasn't sure how else to phrase it.</p>
