I'm almost sure that's documented somewhere, but I can't remember where.
I think it's in the "beginner's guide to unix" but that's just a guess.
Actually, it's kinda neat because even if someone removes the directory
you're working in the null name still gets it opened (since it bypasses
all the other stuff in nami()).
