Re: [PATCH v2 22/43] refs-be-files.c: add do_for_each_per_worktree_ref

> Alternate refs backends might still use files to store per-worktree
> refs.  So the files backend's ref-loading infrastructure should be
> available to those backends, just for use on per-worktree refs.  Add
> do_for_each_per_worktree_ref, which iterates over per-worktree refs.
