This patch leaks internal implementation details into the public refs
interface. I want to make sure that code elsewhere in Git treats these
structures as opaque. That is why I suggested creating an extra module
to hold "protected" code for the reference backend "class hierarchy" [1].
For a sketch of what my suggestion would look like, see the two commits
at the tip of branch "refs-be-common" on my GitHub repo [2].
