Well, if I may add a data point, it happened to me various times
of getting in trouble with os.system and quotes when managing
Windows files. I know about os.spawn*, but it is a knowledge that
keeps escaping from my mind. I would keep os.system as it is,
but I would modify the documentation (or maybe the docstring of
os.system) pointing out the existence of os.spawn*.
Just my 0.02c,
