[issue39899] `pathlib.Path.expanduser()` does not call `os.path.expanduser()`

[Barney Gale]

New submission from Barney Gale <barney.gale at gmail.com>:

`pathlib.Path.expanduser()` does not call `os.path.expanduser()`, but instead re-implements it. The implementations look pretty similar and I can't see a good reason for the duplication. The only difference is that `pathlib.Path.expanduser()` raises `RuntimeError` when a home directory cannot be resolved, whereas `os.path.expanduser()` returns the path unchanged.
