Merge branch 'pb/recurse-submodule-in-worktree-fix' into maint

The "--recurse-submodules" option of various subcommands did not
work well when run in an alternate worktree, which has been
corrected.

* pb/recurse-submodule-in-worktree-fix:
  submodule.c: use get_git_dir() instead of get_git_common_dir()
  t2405: clarify test descriptions and simplify test
  t2405: use git -C and test_commit -C instead of subshells
  t7410: rename to t2405-worktree-submodule.sh
