I tried switching from `optparse` to `argparse`, but ended up reverting back because `argparse` does not respect double quotes.  For example, `optparse` correctly parses the following, while `argparse` does not:

   python myprog.py --ng --INP="Demo IO"

(`argparse` splits "Demo" and "IO" into separate tokens).

Can you submit some example code that shows this? I can't reproduce this with:

---------- temp.py ----------
import argparse

parser = argparse.ArgumentParser()
parser.add_argument("--ng", action="store_true")
parser.add_argument("--INP")
print(parser.parse_args())
------------------------------

$ python temp.py --ng --INP="Demo IO"
Namespace(INP='Demo IO', ng=True)

Hello Steven,

I'm embarrassed to report that I can't reproduce the problem.  The
input line is parsed correctly if I enclose the string 'Demo IO' in
double quotes.  It is parsed incorrectly if I enclose it in single
quotes, but it looks as though this is the fault of the Windows shell,
and not Python.

My apologies.

Phillip

Closing then. Thanks for checking it again!
