Thanks for the suggestion, this is a very good idea.

An "exit function" returned by `set-transient-map' is a clever thing,
without such returned function it would be more complicated to implement.
I quickly tried it out, and it works indeed.

A new user option could be named `repeat-exit-timeout'.
