Uh ah, I overlooked this in the above citation: After a file (of any mode) =
is *opened*,=20
But the next sentence for Append does not make it clear whether this applie=
s only to Open. It sounds like the old contents are saved for both, Open an=
d Create.
So very bad wording here. But it makes sense that Create creates a new (hen=
ce empty) file.
