Hello,

I just tried running master (v2.9) on Windows and it mostly works, but some arguments seem to be ignored? -r is heeded and -x is processed but ignored while -d, -m and -w have no effect. However, the flags appears to be set properly internally, per the output from this basic debug.patch:

D:\Tools\>c:\Progra~1\Python\python -V
Python 3.9.1
D:\Tools\>c:\Progra~1\Python\python imgp-master\imgp --mute --quality 90 -x 800x800 --overwrite -r imgp
90
True
True

Non-flag heeding invocation output pre-debug patch (identical with short or long-form parameters):

D:\Tools\>c:\Progra~1\Python\python imgp-master\imgp --mute --quality 90 -x 800x800 --overwrite -r imgp.test
imgp.test\10_PHOTO1\R_12fwK7duntjbSI9_IMG_0145.jpg
1280x960 -> 1280x960
396696 bytes -> 173783 bytes

Any ideas?
