Summary: Problem parsing cmdline parameter quoted with a trailing \

Initial Comment:
This problem happens in launching Python from Windows. 
A quoted pathname is used as parameter. If and only if 
the pathname is ended with a trailing \, it is treated 
as an escape character.

p.py
-------------------------------------------------------
import sys
from pprint import pprint
pprint(sys.argv)
-------------------------------------------------------

Note slash inside the quote is treated as path 
separators

g:\usr\bin>c:\python24\python.exe  g:\usr\bin\p.py "
tung\wai\yip" wai
['g:\\usr\\bin\\p.py', 'tung\\wai\\yip', 'wai']


However the trailing \ is treated as an escape 
character for the quote. Only command line parameter 
is presented in sys.argv.

g:\usr\bin>c:\python24\python.exe  g:\usr\bin\p.py "
tung\wai\yip\" wai
['g:\\usr\\bin\\p.py', 'tung\\wai\\yip" wai']

Is that Python-specific? I thought sys.argv is the cmdline
args as Python gets them from Windows.
