Great, thanks!

Preview:

- Project progress: where I discuss a rough plan for making ’git
submodule’ a
  true builtin.

So your plan is the following:

  - Rename git-submodule.sh to git-submodule-legacy.sh.
  - Create builtin/submodule.c, that will read from a config switch
called ‘submodule.useBuiltin’. If this is set to false, just call the
legacy shell script, else use the builtin versions.
  - Copy the functions from builtin/submodule--helper.c to
builtin/submodule.c one by one. Make necessary changes in the flag
parsing.
  - Once all the functions have been successfully copied, make the
default value of submodule.useBuiltin to true.
  - …eventually remove submodule--helper.c and the shell script
entirely, and deprecate the ‘submodule.useBuiltin’ option.

I wonder though how in the tests you are going to check both the new
builtin submodule and the old git-submodule.sh? Do you plan to run the
tests twice (once with submodule.useBuiltin set to true, and once with
it set to false)?
