I personally do not know any windows program I care about that
can't deal with slashes. My local hack makes 'stat' always output 
slashes and I am completely happy with it.
Slash option in the [ui] sounds like a proper solution though.

Yes, for me 'stat' is the only command where this really matters, but
I do not script too much.
