[PATCH v3 0/1] [BUG] refs: verify does not work if there are v2.43.0 or older worktrees w/o wt. refs

[shejialuo <shejialuo@gmail.com>]

Hi All:

Changes in v2:

1. Update the commit message to incorporate the commit message that
introduces the BUG to better explain.
2. Update the shell script to avoid hardcode gitdir path.
3. Change "rm -rf" to be "rmdir", which would be safer because we should
delete an empty directory, which has a better semantics.

---

Changes in v3:

1. Use subshell for test style.

Thanks,
Jialuo
