+This test creates a working tree state with a file and subdir:
+
+  top (committed several times)
+  subdir (a subdirectory)
+
+It creates a commit-hook and tests it, then moves .git
+into the subdir while keeping the worktree location,
+and tries commits from the top and the subdir, checking
+that the commit-hook still gets called.'
