tests: cosmetic improvements to the repo-setup test

Give an overview in "sh t1510-repo-setup.sh --help" output.
Waste some vertical and horizontal space for clearer code.

-# 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 is only effective if GIT_DIR is set
-#    Uneffective worktree settings should be warned.
-#
-# 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.
