	* 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.
