I'm sorry, I was wrong saying "does not work".  The problem is not
that it does not work, but that you need to take care of exit 
condition to correctly support detached HEAD state, and not end
with empty name for a branch, for example...

But if handled correctly, git-symbolic-ref is as good as git-rev-parse
as a plumbing to resolve current branch name.

Best,
