[issue10684] Folders get deleted when trying to change case with shutil.move (case insensitive file systems only)

[Heikki Toivonen]

You can't solve this by trying to do different things on different operating systems. This bug depends on file system properties, not OS.

Also I don't think you can just lower case the path and do a comparison, because there are funky characters that don't round trip lower->upper->lower. And you certainly can't do this for just the last component of the path name - any component of the path could have changed case.

I still think the best avenue would be to first try straight os.rename, and if that fails (maybe only if target exists), the logic that is currently in shutil.move.
