Pavel Labath 238169db60 Fix windows unit tests
The unit test I added in the previous commit discovered a bug in
PrependPathComponent on windows -- it was calling SetFile with the host native
path syntax, whereas it should be explicitly specifying the path syntax (as
AppendPathComponent does). This fixes it.
