100% agreement: with the proliferation of network-mounted filesystems,
there's no longer a deterministic way to infer whether a filesystem is
case-sensitive or not from the OS brand.  Instead, we should query the
filesystem about that, and the function suggested by Stefan should do
that (when there're no file-name-handlers for the filesystem).
