Btw, to expand on that - one of the nice things from this whole re-org of
how we handle refs is that when you do
git-rev-parse --all
it now sorts them in a reliable order - by name. Before, they came out in
some random order that totally depended on the filesystem that the
references were on.
Use the "--symbolic --all" to see this in a more obvious way, before and
after.
