As I guessed, it's not easy to find the right place(s) to put a prompt
before state changed or undoing state is easy.  May I suggest that we move
ahead with the patch I've attached and consider enhancements that may
include a prompt at a later time?  We can also see how people get on with
the tab-bar-lines condition vs. just tab-bar-mode (which I still prefer)?
