Wrong `EditorConfig_python_files_dir` when open file via command-line on Windows.

Call example:
```
C:\> vim "[FILEPATH]"
```

Error code:
```
Faild to execute " "python" "C:\/main.py" "[FILEPATH]"". Exit code: 2
Message:
['(null): can''t open file ''C:\/main.py'': [Errno 2] No such files or directory']
```
