[Zope] lines property issue

[David Chandek-Stark]

I understand how splitlines() works -- just don't understand how Zope 
gets '\n' from an empty value. E.g., if you submit a form with an empty 
  <textarea> element, the resulting value should be an empty string '', 
which splitlines() would turn into [].
