You could override the "epemeral" methods and call [self
updateChangeCount:NSChangeUndone] after calling super. That would leave the
operation on the undo stack, but leave the document's change count, um...
unchanged. :-)
Or, you could keep track of the "real" changes yourself, and override
-isDocumentEdited with your own implementation.
