Yes and no, The bundle includes both the full final thing, and each
step along the way. Each step along the way is something you'll get
when you merge it.

Once merged, it will be "next one" in the description above. It would
typically look something like this in "bzr log"(shortened)  In this
example, doing C requires doing A and B as well...

committer: foobar at foobar.com
message: merged in C
      -------
      committer: bar at bar.com
      message: opps, fix bug in A
      -------
      committer: bar at bar.com
      message: implement B
      -------
      committer: bar at bar.com
      message: implement A

So, you'll get full history, including errors made :)  You can also
see who approved it to this branch (foobar) and who did the actual
work (bar)
