I think that does make some sense, but do you have a specific scenario
in mind?  What kind of prompt would help the user more than the standard
prompt here?

It's a slightly non-compatible change, but I think it sounds unlikely to
be bothersome (as you point out).

Anybody else have an opinion here?
