Yes, that seems to fix it. 

Two more questions/comments.

- Should n-d-s-review-patch update to current master? perhaps with
  prefix?

- I think more escaping of branch names is needed. In particular, branch
  names with {} in them get created ok, but then don't work very well in
  magit.  E.g. running log I get "Args out of range: "face}s", 5, 10"
  with the branch name
