Perhaps a more general solution would be possible here. I think there
probably are other "mostly-read-only" modes where you have one or two
special commands that alter the buffer, anyway. Like with `M-k'.
Perhaps there could be a buffer-local variable like
`undo-read-only-buffer' that if set, would allow `undo' to work in these
cases.
