Yes, though there are nits below.

git-mv failing seems like a new possibility without incurring
another process spawn with the new repository object.
(Though then we could also just fix the recursed submodule)

We seem to have different styles for nested shell. I prefer
outside command &&
(
first nested command here &&
...
as that aligns indentation to the nesting level. I have seen
the style you use a lot in the test suite, and we do not have
a guideline in Documentation/CodingGuidelines, so I do not
complain too loudly. ;)

So far a nice setup!

This is the offending command that produces the bug,
as it will break most subsequent commands, such as
>> + git status
git-status is one of the basic commands. Without
status to function, I think it is hard to recover your repo without
a lot of in-depth knowledge of Git (submodules).
I wonder if git-status should complain more gracefully
and fallback to one of --ignore-submodules={dirty, all},
that actually still works.
Maybe we could introduce a new default mode for this
flag, that is "none-except-on-error", though this sounds
as if we're fixing symptoms instead of the root cause.
