Vector.java (ensureCapacity): Don't increment modCount.

2000-11-27  Bryce McKinlay  <bryce@albatross.co.nz>

	* java/util/Vector.java (ensureCapacity): Don't increment modCount.
	(addElement): Don't increment elementCount twice. Doh.
	* java/util/ArrayList.java (add): Only call ensureCapacity if the
	array needs to be expanded.
	(addAll): Ditto.
	* java/util/Collections.java (UnmodifiableCollection): Implement
	toString().
	(UnmodifiableList): Throw UnsupportedOperationException from
	modification methods. Set `l' from the one-parameter constructor.
	(UnmodifiableMap): Implement toString().
	(SynchronizedCollection): Ditto.
	(SynchronizedList): Set `l' from the one-parameter constructor.
	(SynchronizedSortedSet): Set `ss' from the one-parameter constructor.
	(SynchronizedMap): Implement toString().
