TextArea.java: Fix indentation.

2004-01-25  Thomas Fitzsimmons  <fitzsim@redhat.com>

	* java/awt/TextArea.java: Fix indentation.  Flesh out javadocs.
	(getMinimumSize (int, int)): Fix FIXME -- return Dimension (0,0)
	when peer is null.
	(setColumns): Remove FIXME -- peer will retrieve number of
	columns by calling getColumns.
	(setRows): Likewise for number of rows.
	(next_text_number): New field.
	(paramString): Fix param string.
	(generateName): New method.
	(getUniqueLong): New method.
