I don't know much about ref handling code (especially after the big transaction update), so i may be wrong, but do we need to invalidate some caches in refs.c after this? The same for update-ref in the other patch. We may need to re-read the index after 'reset --hard' too if we ever need to do touch the index after that (unlikely though in the case of 'worktree add')
