Could you elaborate on this point? I'm not sure to what exactly it is 
you're referring.

Actually I don't really know why I even called it that, since it was 
never really a header, just by analogy with scanf.h I suppose :-), but 
see below...

The attached patch addresses these points, does it look any better?
I haven't tested it too rigorously yet, since I wanted some feedback 
without first spending ages checking it extensively, but it seems to be 
fine - just have to make sure I haven't forgotten some corner cases.

I still don't really know what I might test here. Maybe try examples of 
cases where the current code does not act like Windows; there are also 
some cases where neither acts like windows (but they seem to have the 
same problems). The problem is I probably wouldn't think of cases where 
my code causes regressions (otherwise it wouldn't do so:-)), and this 
isn't really something in which you can enumerate all the different 
combinations of options (at least without infinite time and patience).
Thanks for your comments,
