Re: [PATCH v3 30/39] builtin/verify-pack: implement an --object-format option

> Since we're not in a repository here, we need to provide git verify-pack
> help to set things up properly.  git index-pack already knows an
> --object-format option, so let's accept one as well and pass it down to
> our git index-pack invocation.  Since this argument is optional, let's
> dynamically determine the proper location to insert it into the array.
> Finally, let's make t5702 pass the proper argument on down to its git
> verify-pack caller.
