[jdom-interest] Still to do - Text 'merger'

     Hello Rolf, All,

  I think most users would be puzzled what it means to "simplify"
text. It sounds as if the text itself is affected, rather than its
representation. I would call it Element.defragmentText(). Many people
know that if you defragment a file, the content stays the same.

     Take care
