After looking at this again, I realized it could be made even more  
generic by creating the UndoableEditListener implementation as a  
regular class (not inner).  That way the ptolemy.actor.gui.TextEditor  
can make use of the same code.  The PythonScript actor seems to makes  
use of the TextEditor when you "Configure Actor" (from the context  
menu).  It would be nice to provide the undo feature there, too.

We could also do something similar with the RExpression actor (but  
instead use the text editor when "Open Actor" is invoked).  Using the  
editor for R would address a few concerns we've heard about the  
current editing window being too small and also demanding window focus  
until the text changes were "committed".
