[PATCH 0/2] Re: git diff --submodule=diff fails with submodules in a submodule

I came up with a patch that fixes the issue locally. (It is the first patch, such that we can track the first patch down to maint)

While doing so, I noticed 2 issues:
* when having nested submodules, we probably want to have --submodule=diff
  to recurse into the nested submodules, so pass on the option.
  (2nd patch)
* the tests in t4060 hardcode hashes literally. I do not have a patch for that
  yet, but I will send patches later. (c.f. "sanitize_output" in t4202)
  
Thanks,
Stefan
