It solves the case which made me write my own overcomplicated patch at 
first. Besides, spending twenty minutes beating os.system() with all 
combinations of quoted executable/quoted arguments, I cannot find any 
your patch does not handle. I suppose there may be one involving 
escaping and special characters and spaces and other stuff, but really 
who cares.

+1 for it.

Tell me if you have tests you would like to run, I would be happy to do it.
