[Python-Dev] Backward compatibility of shutil.rmtree

It would be os.flistdir instead of os.listdir, not os.fwalk, right?

The way this interface is defined, it's IMO best to do "precise"
reporting, i.e. pass the exact function that caused the failure.
I'd weaken the documentation to just specify that the error-causing
function is reported, indicating that the exact set of functions
may depend on the operating system and change across Python versions.
