Besides, if I understand the use of __git_refs correctly, it is
primarily about completing things like
git checkout -b topic origin/<TAB>
where you actively want _local_ copies of what you currently have in
refs/remotes/origin/, not what you would get if you were to fetch
and then type the command again, so in that sense, using ls-remote
is a wrong thing to do in the first place.
This however may need to be made optional if this is also being used
to complete
git fetch git://g.k.org/pub/scm/git/git.git/ <TAB>
to list what can be fetched, but I do not think that is a very
common thing to do (you either know what you want to fetch, in which
case you do not complete but copy & paste, or more likely you have a
named remote and fetch the whole thing).
So I think overall the above makes sense.
