After spending too much time on this stupid VCS...  this is what I have
figured out that actually works, gives the right 'bzr revno' and does
not alter the original copy.

Download:
bzr branch "$url" "$dir" --no-tree --use-existing-dir

Update:
bzr pull "$url"    (--overwrite ??)

Create local working copy at a given revision:
bzr checkout "$dir" -r "${revision[@]}"

Update local copy to given revision:
bzr pull "$dir" -q --overwrite -r 80
bzr clean-tree -q --detritus --force


I will adjust the patch from Lukáš to use these commands unless someone
tells me that I missed something.
