Glen pointed out an issue in ab/submodule-no-abspath which I just
submitted a fix-on-top for in [1].

There will be a merge conflict with ab/remove--super-prefix, but one
which I tried to make easy to resolve when crafting [1]. The resolution
is:
	
	diff --git a/submodule.c b/submodule.c
	remerge CONFLICT (content): Merge conflict in submodule.c
	index ab2e61617d8..08366045ffe 100644
	--- a/submodule.c
	+++ b/submodule.c

Now, I expect that neither topic will make this upcoming release, and
"ab/remove--super-prefix" will have at least one more re-roll per Glen's
outstanding feedback.

Would you like to have such a re-roll sooner than later, and to have
"ab/remove--super-prefix" built on "master" the existing
"ab/submodule-no-abspath", or rebased for this fix-on-top? Or I could
just wait until after the release when the dust settles and
"ab/submodule-no-abspath" + this fix on top in [1] graduate to submit a
v4.
