No doubt. Itʼs a *very* long thread.

Oh. Is that what non-emacs-experienced users really expect?

Right, so if we find a good way to fix that itʼs fine, although Iʼm
not sure whether thereʼs any good reason for us to do it other than
'other programs do it' ; the current behaviour seems consistent
enough.

Only to people who create buffers, and then later decide whether to
put stuff in a file. Thatʼs not your typical newcomer to emacs.
