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.
