Re: [PATCH 00/13] submodule: convert the rest of 'update' to C

This series builds upon the previous conversion work on 'submodule update' and
moves out all of that shell logic in 'git-submodule.sh' into
'builtin/submodule--helper.c'.

Hey Atharva! I'm working on a series that will teach "git branch" how to
handle "--recurse-submodules". I plan to do this in-process because I
think this will take less overall effort than using child processes, and
to make it happen, I'm planning to add a helper function like
"for_each_submodule()", which would call a C callback function on each
submodule.

This is conceptually similar to "git submodule foreach" and
for_each_listed_submodule() (though not exactly equivalent), so I'm
reaching out to you in case this work is already on your radar. If so,
and if it is coming soon, it might be easier to for me to base my work
off yours instead of duplicating our efforts :)

Thanks for reaching out. I don't have anything like this on my radar, so
feel free to go ahead with your plan :)
