[PATCH/RFD 0/3] worktree.* config keys and submodule and multiple worktrees

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

1/3 is a more complete version of a patch I posted earlier [1]. It
makes sure that worktree.* config keys are stored in a different place
than $GIT_DIR/config. This allows us to work around the core.worktree
issue in multiple worktree setting.

I think 1/3 and 2/3 are fine. 3/3 is probably not. It's more of a
proof of concept. The tests pass, but there's no migration path for
existing submodules. Submodules modified by new Git will confuse old
Git because the old ones do not understand worktree.path (the
replacement for core.worktree)

But I think it's a start..

  submodule: use worktree.path instead of core.worktree
