And more to the point, this is just one reason why one should use
for-each-ref when scripting (the other is that git-branch's output is
considered porcelain, and is not guaranteed to remain stable). E.g.:

  git for-each-ref --format='%(refname:short)' refs/heads/

would produce the output the original poster wanted.
