[python-win32] does pipes.quote() work properly on Windows?

There also seems to be an undocumented function (not a method, as the
docs erroneously mention in passing) in the "subprocess" module, called
"list2cmdline", which appropriately quotes things for win32's
CreateProcess().  Interesting to see that both functions do the same
thing:

MARLOWE-VM:~ $ python -i
Python 2.6.5 (r265:79096, Mar 19 2010, 21:48:26) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> subprocess.list2cmdline(["That's the game! says Mike \"Hammer\" Brotsky"])
'"That\'s the game! says Mike \\"Hammer\\" Brotsky"'
>>> import pipes
>>> pipes.quote("That's the game! says Mike \"Hammer\" Brotsky")
'"That\'s the game! says Mike \\"Hammer\\" Brotsky"'
>>> 

And the code in Twisted generates the same thing:

>>> import win32
>>> win32.quoteArguments(["That's the game! says Mike \"Hammer\" Brotsky"])
'"That\'s the game! says Mike \\"Hammer\\" Brotsky"'
>>>
