Even if the bulk of cygwin wasn't using the win32 api, we've already seen
what happens when we create files which can't be manipulated with standard
windows programs.
Maybe at some point we'll have a "semi-managed" mount (because, as you all
know managed mounts are terrifically bad because it's possible that they
will run into the path length limitation more quickly than regular mounts*)
but I don't think we should ever go down the path of blithely creating files
with special characters by default.
