Yes, an undo record of a persistent buffer only keeps a version of the buffer
(effectively, just a pointer because the contents is also part of newer buffer
versions). An undo record of a regular buffer only keeps an editing operation,
I think. So, perhaps you could rewrite that portion and say that only a pointer
is kept instead of an editing operation object...
