I see that ab/no-more-git-global-super-prefix has landed in "next", I
was planning to submit the built-in submodule topic after it, i.e. the
change to get rid of git-submodule.sh.

But the post-cleanup in that topic of moving the relevant code from
builtin/submodule--helper.c to builtin/submodule.c would conflict with
ab/config-multi-and-nonbool, as some of it uses the *_multi() API.

Now, it would be relatively easy to solve those conflicts, but I'd also
like to make it easier for you, Junio.

So more reviews on that topic would be most welcome. It fixes quite a
few segfaults we currently have in-tree, so I'm a bit surprised at the
relative lack of interest.
