-test_description="Tests of cwd/prefix/worktree/gitdir setup in all cases
-
-A few rules for repo setup:
-
-1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
-   GIT_DIR.
-
-2. .git file is relative to parent directory. .git file is basically
-   symlink in disguise. The directory where .git file points to will
-   become new git_dir.
-
-3. core.worktree is relative to git_dir.
-
-4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
-   equivalent to GIT_WORK_TREE.
-
-5. GIT_WORK_TREE/core.worktree was originally meant to work only if
-   GIT_DIR is set, but earlier git didn't enforce it, and some scripts
-   depend on the implementation that happened to first discover .git by
-   going up from the users $cwd and then using the specified working tree
-   that may or may not have any relation to where .git was found in.  This
-   historical behaviour must be kept.
-
-6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
-
-7. Effective core.worktree conflicts with core.bare
-
-8. If GIT_DIR is set but neither worktree nor bare setting is given,
-   original cwd becomes worktree.
-
-9. If .git discovery is done inside a repo, the repo becomes a bare
-   repo. .git discovery is performed if GIT_DIR is not set.
-
-10. If no worktree is available, cwd remains unchanged, prefix is
-    NULL.
-
-11. When user's cwd is outside worktree, cwd remains unchanged,
-    prefix is NULL.
