"Change Set:		SortedCollReversed
Date:			16 October 2001
Author:			Göran Hultgren

BugFixing Party @ Camp Smalltalk OOPSLA 2001.

Makes sure that SortedCollection>>reversed returns an OrderedCollection
instead of a SortedCollection which would be an inconsistent state.
Inspect this (before the change) to see the problem: (#(1 2 3)
asSortedCollection reversed) add: 4; yourself"!
