[PATCH v2 00/12] Fix git-gc losing objects in multi worktree

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This is basically a rebased version after a lot of changes in
nd/files-backend-git-dir. Thanks to test-ref-store.c, I found and
fixed a bug in for_each_reflog in v1 code.

This series needs latest nd/worktree-kill-parse-ref [1]. But you can
get everything on my github fork, branch prune-in-worktrees-2.
