Oh shoot, I think I was wrong and you are right: the shell redirection
problem is for the case of using the PATHEXT stuff. I.e. I think shell
redirection works fine with a .bat or .cmd stub. Sorry about causing
confusion.

I tend to copy python.exe to pythonXY.exe (as appropriate) after I
install a new Python. I'm considering doing this by default in the
ActivePython installers I make. (Similar to the pythonX.Y executable
copies that get made on Linux/Un*x.) What do you think?

Agreed.

That's too bad. I didn't know "-m" didn't support that... but then I
haven't really used it that much yet.
