According to the documentation for `os.rename`, it already fails on
windows if the target exists (though I do not know if it also fails
on e.g. NFS or across filesystems), which seems to be the behavior
desired for "move2".

So there is no real reason to discuss it, unless there are tricky
edge cases in its behavior.
