This works for multiple worktrees. But scripts may have harder time
getting the path. The recommended way is "git rev-parse --git-path
refdb" but because "refdb" is not registered in path.c:common_list[],
that command becomes git_path("refdb") instead of
get_refdb(get_git_... like here. And I will need to know that
.git/refdb is _not_ per-worktree when I migrate/convert main worktree
(it's very likely I have to go that route to solve .git/config issue
in multi worktree).
The solution is register refdb to common_list[] and you can do
git_path("refdb") here. But then what happens when another backend is
added? Will the new backend use the same path "refdb", or say
"refdb.sqlite"? If all backends share the name "refdb", why can't we
just reuse "refs" instead because the default filesystem-based backend
is technically just another backend?
