Re: [PATCH v3 1/4] clone: update submodule.recurse in config when using --recurse-submodule

[Mahi Kolla <mahikolla@google.com>]

definitely struggled a bit with understanding how to submit patches
and how to amend commits versus stacking changes across commits. Thank
you for your patience! :)

That makes sense, will update.

I will definitely update the 'git-clone' man page to include some
documentation on this change. Should the "advice" to the user show up
in the output message once the clone command is run?

Ah, thank you for pointing me to the right testing function.
Definitely, agree with the single patch. I'll update the corresponding
files and submit them all as one V2 patch.

Thank you so much!
