[Python-ideas] Implementation of shutil.move

[David Townshend]

The behaviour is platform dependant only because it uses os.rename. The
implementation is independent of platform so any change would affect all
platforms. This might not matter if os.link behaves the same across them all
though.

Initially I thought it would be better to use an argument, but having had a
look at the code I'm not so sure any more, since it could end up as two
different implementations in the same function. Also, I'm not so sure its a
good idea to have an optional argument (never_overwrite) that defaults to
False for backward compatibility, but should usually be set to True for safe
behaviour.

platform-dependent and dome platforms already behave as proposed, so the
proposal really unifies the behaviour across platforms.
