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.

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 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.
