	* java/text/CollationKey.java
	(collator): New member.
	(CollationKey): New argument for parent collator.
	(equals): Check for same collator, source string and key array.
	* java/text/RuleBasedCollator.java:
	Reformated.
	(RuleBasedCollator): Don't re-initialize frenchAccents with default
	value.
	(getCollationElementIterator): Rewritten.
