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.
