To address your first complaint, I think it makes perfect sense to
behave differently based on whether an argument has been supplied.
The existence of a pattern tells you something about the user's
intention in issuing the command. If they provide a pattern, they
probably want to /search/ for something. If they don't provide a
pattern they probably want to get a /listing/ of some set.
