   8# A few rules for repo setup:
   9#
  10# 1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
  11#    GIT_DIR.
  12#
  13# 2. .git file is relative to parent directory. .git file is basically
  14#    symlink in disguise. The directory where .git file points to will
  15#    become new git_dir.
  16#
  17# 3. core.worktree is relative to git_dir.
  18#
  19# 4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
  20#    equivalent to GIT_WORK_TREE.
  21#
  22# 5. GIT_WORK_TREE/core.worktree is only effective if GIT_DIR is set
  23#    Uneffective worktree settings should be warned.
  24#
  25# 6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
  26#
  27# 7. Effective core.worktree conflicts with core.bare
  28#
  29# 8. If GIT_DIR is set but neither worktree nor bare setting is given,
  30#    original cwd becomes worktree.
  31#
  32# 9. If .git discovery is done inside a repo, the repo becomes a bare
  33#    repo. .git discovery is performed if GIT_DIR is not set.
  34#
  35# 10. If no worktree is available, cwd remains unchanged, prefix is
  36#     NULL.
  37#
  38# 11. When user's cwd is outside worktree, cwd remains unchanged,
  39#     prefix is NULL.
