Strange as it may seem, there have been issues with other Windows 
command processors, and one in particular (I can never remember which 
one) messes up IO redirection when the pathext mechanism is used to 
select the executable that processes the Python file.

So I would tend to suspect yet another variation on this familiar theme 
given your testing results. But I don't intend to tangle with Vaster any 
sooner than I must.
