Uhm, I misread gitweb output... So, cocoon really has remotes/trunk, so that Peter's original suggestion would work. If the cocoon git-svn clone isn't going to change then Peter's way of doing it might be the best: it ensures that future pulls from origin (cocoon) will update the correct refs so that you can pull/fetch from the git-svn clone (fast) and then git-svn rebase rather than git-svn rebasing directly, which would fetch new commits from the svn repo first (slow).

I think all in all it shows that git-svns default location for branches is not the best choice: they're not local, but they're no "proper" remotes either (unless you use --prefix).
