v2:
* Instead of storing the depth, we keep a boolean `shallow` field in the
  `.gitmodules` file.
* slightly renamed options (--recommend-shallow instead of --recommended-depth)
* one more test
* I dropped [PATCH 1/3] submodule update: make use of the existing fetch_in_submodule function
  as Junio picked it up separately as sb/submodule-misc-cleanups

v1:
Sometimes the history of a submodule is not considered important by
the projects upstream. To make it easier for downstream users, allow
a field 'submodule.<name>.depth' in .gitmodules, which can be used
to indicate the recommended depth.

Thanks,
Stefan
