Instead of -f which for most users looks like some kind of "force"
option maybe --all would be better?

The new default (only most recent version and all installed) is a good
thing.

When I was playing with it I remember that pkg.get_name() already
provides you with packages sorted by version with a most recent one
being returned first. So instead of doing sorting again in
last_inventory() something like below is sufficient and probably more
lightweight.

    list_inventory()
        last_name = ""
        [...]

                                if pf != last_name:
                                        msg(fmt_str % (pf, pkg.get_version(),
                                        state["state"], ufix))
                                elif state["state"] == "installed":
                                        msg(fmt_str % (pf, pkg.get_version(),
                                        state["state"], ufix))

                                last_name = pf
