[PATCH 0/3] Submodules: have a depth field in the .gitmodules file

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.

Stefan Beller (3):
  submodule update: make use of the existing fetch_in_submodule function
  submodule-config: keep `depth` around
  submodule update: learn `--recommended-depth` option
