Those messages are from git-update-ref.  What were some of the messages
from git-svn leading up to that point?

You should never, ever modify the git-svn-HEAD branch yourself.
Interface branches should never be modified.  It's the golden rule of
interfacing between different SCM interfaces.  Sorry, I've been doing
things like this this for a while now I guess I didn't make it
abundantly clear in the documentation.

Save your current work in git-svn-HEAD to a private branch

	git branch -b private git-svn-HEAD

then reset git-svn-HEAD to the last revision where it was managed by
git-svn fetch:

	git-checkout git-svn-HEAD
	git-log (look for the last commit with 'git-svn-id:' in it)
	git-reset --hard <last commit with 'git-svn-id:' in it>

Now go to your private branch:

	git checkout private

And continue working on your private branch as usual.
