Does this countradict POSIX, meaning that when POSIXLY_CORRECT, 'touch -'
should be the same as 'touch ./-'? I couldn't see anything in POSIX that
permits or forbids this change in semantics, although I agree that it
seems useful. Also, it seems a bit strange that - maps to stdout, when it
usually maps to stdin.
