core.worktree is "you tell us where the working tree is" in the above.

That should be more or less what we have been doing since the first day we
started supporting git operations from subdirectories around d288a70
([PATCH] Make "git diff" work inside relative subdirectories, 2005-08-16).

It is possible that we might have broken some over the course while adding
core.worktree and GIT_WORK_TREE support, but I doubt it.
