    There are other modes facing the same problem. For example
    `desktop-save-mode' uses a lock file and asks the user what to do.

Maybe the same approach would be good for preserving *scratch*.  But
this suggests another idea: ask the question just once and have it
apply to all features to preserve anything and everything from a
previous session.
