The formula that I've stumbled onto that appears to work, even with 
arguments with embedded spaces, is this:

         ""cmdname" "arg1" "arg2" ..."

where the string passed to os.spawn or os.popen is indeed entirely wrapped 
in quotes. I think this works because the argument is passed to cmd for 

The annoying thing is that this introduces a nonportability, where for 
win32 the whole thing is quoted, but for linux it cannot be.
