The other (similar) case is for tag objects. When you do "git ls-remote" 
on the remote repo, it will tell you both the tag object SHA and the 
object SHA of the thing it points to, so you can then do a git protocol 
exchange where you do a 

	for_each_tag
		"want <tagsha1>"

	for_each_tag
		"have <objectitpointstosha1>"

and you'll get just the tag object back.
