Couldn't find anything in my mail archive. But the idea is simple:
 - we delay detaching HEAD until we need to update the associated ref
at commit/reset time
 - currently refs/tags/* are read-only. we generalize it to allow this
'read-only' attribute on some refs/heads/* as well. Because we can't
really add attributes to refs, config var could be used.
