Write helper functions for t7002 to reuse some code. 2. Refactor/decouple the if/else-if checking chain. 3. Separate out the 'update_mode' refactor into a single commit. 4. Stop using update_sparsity() and instead update the SKIP_WORKTREE bit for each cache_entry and check it out to the working tree. ## Limitations ## At this point, we still don't have in-cone to out-of-cone move, which I don't think is too much a problem, since the title says this series is around out-of-cone as the . But I think it worth discuss if we should implement in-cone to out-of-cone move, since it will be nice (naturally) to have it working. However, I noticed this from the mv man page: "In the second form, the last argument has to be an existing directory; the given sources will be moved into this directory." I think trying to move out-of-cone, the last argument has to be an non-existent directory? I'm a bit confused: should we update some of mv basic logic to accomplish this?
