        It is up to the team that designs clients and servers to build
in warnings and internal logic into all the clients so it is aware of
every other OS combination and warn the user: if you commit this, OS x,
y, z will have the following problems with it. Start with the OSs we
currently support and add more support as new OSs come into the fold.

        Java has a local-independant case-folding function. Why can't
Subversion's portability layer provide the same sort of thing?
