So... the idea is that the caller gives a ref-store and tells these
functions to iterate over refs in it, and the existing submodule
related callers can prepare a ref-store for the submodule---that
way, refs.[ch] layer does not have to _care_ that the set of refs it
was asked to look at is for submodule processing.

Nice.  Very nice.
