Yes, this works... a whole slew of Wahey's. :-)  So it's not a bug, but this 
behavior is still a bit confusing, at least on Windows (as opposed to other 
platforms where it seems to work as expected). Is this the desired behavior? If 
I understand correctly, then registering any function or class in path_hooks is 
useless on Windows for path "", since it will be bypassed.
