What counts as "needing" an object? Does 'git log -Sfoo' or 'git log --stat' need all missing blobs? I'd personally dislike having such commands automatically result in huge downloads, but I'd probably dislike the automatic downloading in general so perhaps I'm just a misfit for the lazy clone usecase. It's still an interesting question though -- what counts as needed?
