When fd47ae6a5b (diff: teach diff to display submodule difference with an
inline diff, 2016-08-31) was introduced, we did not think of recursing
into nested submodules.
When showing the inline diff for submodules, automatically recurse
into nested submodules as well with inline submodule diffs.

I would think this goes on top of origin/sb/show-diff-for-submodule-in-diff-fix.
Thanks,
Stefan
