Re: bzr repository ready?

[Richard Stallman]

    No.  In principle, a checkout is not a branch at all.  It contains the
    working tree, but no history, and by default only enough metadata to
    tell bzr which repository to get history and other metadata from.
    Since the parent repository may be on another host, "log", "diff", and
    "commit" become expensive operations, and pull and push are no-ops.

In a checkout, what do you get in the way of change log information?
I saw this

    Then you cd to your local copy of the mainline branch, merge that
    branch into it, and push to the public repo.  By default bzr log will
    show only that the whole branch got merged, but someone who is curious
    can see the detailed history.

So there is the brief info that you get with `bzr log', and the full info
you can see somehow.  Does the lightweight checkout include either of these?
