 "git fsck" becomes more careful when checking the refs.

I haven't yet found the time to have a look, but hope to do so tomorrow.

* ds/backfill (2024-12-20) 6 commits
 - backfill: assume --sparse when sparse-checkout is enabled
 - backfill: add --sparse option
 - backfill: add --min-batch-size=<n> option
 - backfill: basic functionality and tests
 - backfill: add builtin boilerplate
 - Merge branch 'ds/path-walk-1' into ds/backfill
 (this branch uses ds/path-walk-1.)

 Lazy-loading missing files in a blobless clone on demand is costly
 as it tends to be one-blob-at-a-time.  "git backfill" is introduced
 to help bulk-download necessary files beforehand.

I had a couple of nits and expect another reroll, but think it's close
to being ready.

* ds/path-walk-1 (2024-12-20) 7 commits
 - path-walk: reorder object visits
 - path-walk: mark trees and blobs as UNINTERESTING
 - path-walk: visit tags and cached objects
 - path-walk: allow consumer to specify object types
 - t6601: add helper for testing path-walk API
 - test-lib-functions: add test_cmp_sorted
 - path-walk: introduce an object walk by path
 (this branch is used by ds/backfill.)

 Introduce a new API to visit objects in batches based on a common
 path, or by type.

I had a single nit, but don't necessarily think that it needs to be
addressed.
