Pitch

I’m proposing we add a isjunction method to os.path and a is_junction method to pathlib.Path. Both would return True if the given path is a junction. On Posix the API would exist, but would always return False as this tends to be a Windows-only thing.

We have similar logic to check for concepts like ismount, islink, etc. So i figure this would fit in.
