Very nice. Seems like the way to go. Together with Kim's changes (which 
I believe adds calls to shell-quote-argument here) this should fix the 
problem.

But I have two questions:

- Is there not a unix style shell for DOS too?
- What rules should be used for applying shell-quote-argument? I mean 
where should it be applied? Should it not be applied as late as possible 
when forming the command line to send to the shell? Do we do that now?

BTW, wonder why this was not implemented before? It looks like the 
function w32-shell-dos-semantics were added already 1998, eight years ago.
