thanks for the clarification. However, my question had a more general
part: Is it OK to simply delete upstream code of *any* package I might
stumble upon from our SVN in case I would stumble upon it = I can safely
assume it is there rather by accident?
I would really like to do so without asking maintainer / list because
usually this code can simply be restored either from upstream or from
spnapshot.debian.org - so no real harm should be caused, thought. If a
maintainer has really good reasons to keep this code I would suggest
droping a file "README.Status" in the branch/ dir to inform others about
this fact.
