[PATCHv2 0/2] Submodule shallow recommendation [WAS: Submodules: have a depth field in the .gitmodules file]

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
