[issue20451] os.exec* mangles argv on windows (splits on spaces, etc)

[Florian Bruhin]

New submission from Florian Bruhin:

The os.exec* functions seem to mangle arguments on Windows. So far I noticed the supplied argv gets split on spaces, and double-quotes get stripped when not escaped.

Example, on Windows 7:

>>> platform.platform()
'Windows-7-6.1.7601-SP1'
>>> os.execlp('python', 'python', '-c', "sys=__import__('sys');print(sys.argv)", 'Hello World')
['-c', 'Hello', 'World']

Same on Archlinux: ['-c', 'Hello World'] as expected.

Both running Python 3.3.3.
