Re: [PATCH v3 0/9] archive: Add --recurse-submodules to git-archive command

Hi Heather!

We covered this series in Review Club [1]. We will leave review on
this thread, though you may find the notes [2] useful.

The Review Club participants generally agreed that this is a really
well-structured and easy-to-follow series :) As far as new contributions
go, this is really good.

I think this series broadly makes sense, i.e.:

- the implementation of plumbing "struct repository" through read_tree()
  (this might also be really helpful for future work)
- the interface (using "--recurse-submodules")
- the expected behavior

So I can see this going through with a bit of polish. The others have
covered style issues quite thoroughly, so I won't comment on those.
