* javax/swing/text/JTextComponent.java
(JTextComponent): Added repaintListener which issues repaint
requests when the underlying document changes.
(setDocument): Adds repaintListener to document when the
document is changed.
* javax/swing/text/DefaultEditorKit.java:
Removed repaint calls on JTextComponent. This is now handled
through a DocumentListener in JTextComponent that repaints
the component when needed.
