Indeed for those very projects that don't use a ChangeLog but do
auto-generate one, it could be a bit annoying.  But I don't think it's
a very serious issue.

Yes.

It could do that, indeed.  Or it could kill the buffer at the end if the
buffer didn't exist earlier.  It seems more trouble than it's
worth, tho.
