[PATCH 0/4] Multiple worktrees vs. submodules fixes

[Max Kirillov]

Hi.

These are fixes of issues with submodules with use of multiple working
trees.

To be applied on top of the $gmane/257559, (6b4ce012cb in current pu).

Max Kirillov (4):
checkout: do not fail if target is an empty directory
submodule refactor: use git_path_submodule() in add_submodule_odb()
git-common-dir: make "modules/" per-working-directory directory
path: implement common_dir handling in git_path_submodule()
