BTW, a typo here: (kbd "M-/") is missing.

Sorry, this part of the feature is still unpolished.
The intention was to disallow repeating of undo with
the key sequence `C-/ u', but allow only with `C-x u u'.
Maybe this was a wrong idea?  Do you think it should be
possible to type `C-/' to initiate the repeating sequence
`C-/ u u u'?
