I've made some local modifications and want to 'git svn dcommit' them so
I 'git svn rebase' first:

 $ git svn rebase

 When you have resolved this problem run "git rebase --continue".
 If you would prefer to skip this patch, instead run "git rebase --skip".
 To restore the original branch and stop rebasing run "git rebase --abort".

 rebase refs/remotes/iteration_5: command returned error: 1

Uh-oh, now I appear to be on 'no branch' and the contents of
thickbox.css aren't marked up with the conflict markers, it appears to
just be the old file without my revisions.  Did I do something wrong?
How do I recover from this state?
