I did a sweep through editor and mailnews to remove these methods. * PeekUndoStack() and PeekRedoStack() now return an AddRef'd pointer. * Removed GetUndoString(), GetRedoString() and Write() from the nsITransaction interface. Neither editor or mailnews really made use of these methods. * Removed Write() from the nsITransactionManager.cpp interface. * The Transaction Manager now supports weak references. * Added support for nsITransactionList to the TransactionManager to allow access to all transactions on the Undo and Redo stacks, as well as auto-aggregated transactions. * Removed all references to nsITransactionDescription from txmgr and editor. * Added nsPIEditorTransaction and made all Editor internal transactions inherit from it so we can distinguish between our transactions and ones from 3rd parties.
