Issue:
`path.Path().files()` fails with `FileNotFoundError`
```python
>>> import path, pathlib
>>> pathlib.Path()
WindowsPath('.')
>>> path.Path()
Path('')
>>> list(pathlib.Path().iterdir())
[WindowsPath('.git'),
 WindowsPath('.idea'),
 WindowsPath('LICENSE'),
 WindowsPath('pyproject.toml'),
 WindowsPath('README.rst'),
 WindowsPath('setup.cfg')]
>>> path.Path().files()

                                                         ^^^^^^^^^^^^^^^^
FileNotFoundError: [WinError 3] The system cannot find the path specified: Path('')
>>> path.Path('.').files()
[Path('.\\LICENSE'),
 Path('.\\pyproject.toml'),
 Path('.\\README.rst'),

```

I expect `path.Path().files()` to work just like `path.Path('.').files()`, but it currently raises error. Is that intentional or is it a bug?
This is not a Windows-specific issue. There is a similar error on my Linux machine: `FileNotFoundError: [Errno 2] No such file or directory: Path('')`.



Discussion / hints:
> Is that intentional or is it a bug?

It's probably neither intentional nor a bug but a yet unexplored use-case ;)

Note that pathlib explicitly replaces the empty constructor with the `'.'` path:

```
>>> pathlib.Path()
PosixPath('.')
```

This project does aspire to align with pathlib where possible, so it should probably do the same (and probably implement `iterdir` at the same time, if it's not present already).
Would you be willing to work on a patch?
