I have no comment on which is the best command to use (you would know
much better than I), but adding "refs/" is wrong.

BTW, one bad thing about the new get_headref compared to the original is
that it does not distinguish very well between "ref does not exist" and
"an error occurred." Is there a lookup command that makes such a
distinction possible?
