Feel free to add commentary that describes the desired behavior in
specific situations.

I don't think how we can have tests for this in the test suite, since
you cannot test this in a batch session.  We could have tests in
test/manual/, though.

I doubt that, as the change is significant and we won't be able to
know if it's right until some time.  It would be wrong to delay Emacs
28.2 until then, IMO, since the situations in which this happens are
somewhat rare and the problems aren't catastrophic.
