Merge branch 'jk/fsck-indices-in-worktrees'
"git fsck" learned to check the index files in other worktrees,
just like "git gc" honors them as anchoring points.
* jk/fsck-indices-in-worktrees:
fsck: check even zero-entry index files
fsck: mention file path for index errors
fsck: check index files in all worktrees
fsck: factor out index fsck
