[PATCH 0/2] index-pack out-of-repo fixups

Coverity reported that the recently-added call to add_packed_git() in index-pack.c actually does nothing. It's right, and it turns out this is a minor bug in the .gitmodules fsck patches in v2.17.1. I say minor because it errs on the side of complaining too much (so it's not a security problem) and it comes up only in what I can imagine is a pretty obscure case.

The second patch here fixes that. But while looking into it, I notice a much older breakage in running "index-pack --strict" outside of a repository entirely. That's fixed by the first patch.

  [1/2]: prepare_commit_graft: treat non-repository as a noop
  [2/2]: index-pack: handle --strict checks of non-repo packs
