 /**
 28  
  * Inserts formatted text (possibly collected using a
 29  
  * {@link org.apache.tapestry.form.TextArea} component. [<a
 30  
  * href="../../../../../ComponentReference/InsertText.html">Component Reference</a>]
 31  
  * <p>
 32  
  * To maintain the line breaks provided originally, this component will break
 33  
  * the input into individual lines and insert additional HTML to make each line
 34  
  * seperate.
 35  
  * <p>
 36  
  * This can be down more simply, using the &lt;pre&gt; HTML element, but that
 37  
  * usually renders the text in a non-proportional font.
