It's mostly small nits here and there, except: - I found that the change I'd made to update-index.c was buggy at the point it was introduced in the series, the object_type would be uninitialized. There were/are no tests for that, but I've moved things around so we don't have that bug anymore. - Elijah had a comment on whether we needed oid_object_info() in blame.c. As it turns out we don't need a "is blob?" check at all there. There's a new 28/29 to refactor that small part of blame.c, along with a test. What this re-roll *does not* include is the final 28-30/30 part of v1 to s/mode/raw_mode/g and move canonical_mode() out of tree-walk.h. So a follow-up series will still be needed to fix the fsck.c check for bad modes, but I wanted to split that tricker change off from this rather big initial refactoring.
