It adds a new element type to buffer-undo-list, `unconfined', which disables selective undo for one record. Consider it a proof-of-concept. > > While it has the advantage of not requiring the user to change any settings, I still prefer the first approach (an option to disable undo confinement), as it's less intrusive and more generally useful. However, this should work as well. Thanks. I don't consider myself an expert on undo, but the patch looks reasonable to me. I think we should describe this new element in the ELisp manual, but other than that, I think it can go in. Stefan, any comments?
