[PATCH 0/3] repack: handle --keep-pack, --max-pack-size for geometric repacks

This series fixes two issues that Victoria and I noticed while working on an unrelated issue yesterday.

  - The first patch comes from Victoria's earlier submission[1], and addresses
    an issue where packs specified as kept via the `--keep-pack` option could
    potentially be removed (without rewriting their objects) during a
    `--geometric` repack.

    The first patch is Victoria's alone, with some minor fixups applied from my
    review in [2]. It's included in this series since it's related, and avoids
    any conflicts when merging.

  - The latter two patches are mine, and address an issue where specifying a
    `--max-pack-size` value during a `--geometric` repack could result in object
    loss because of a false positive in our "did we write a pack with this
    name?" check (which can occur when the list of packs we wrote isn't sorted).

    The first of these two patches demonstrates the issue (done in a separate
    patch, since the scenario is quite involved), and the second patch fixes the
    bug.

Thanks in advance for your review.
