OK, singling out that manifest file is just nonsense, any object file,
etc... in the nested worktree/repo can trigger the same issue just as
well.
(It just so happened that when I ran 'git clean -fd' I had a nested
worktree where I haven't build anything yet, and besides the .git file
only that 'git.manifest' file survived in the nested worktree, and then
I got misled by it.)
