The `es/worktree-repair-copied` topic added support for repairing a
worktree from a copy scenario. I noted[1,2] that the topic added the
ability for a repository to "take over" a worktree from another
repository if the worktree_id matched a worktree inside the current
repository which can happen if two repositories use the same worktree name.
This series teaches Git to create worktrees with a unique suffix so
that the worktree_id is unique across all repositories even if they have
the same name. For example creating a worktree `develop` would look like:
foo/
├── .git/worktrees/develop-5445874156/
└── develop/
bar/
├── .git/worktrees/develop-1549518426/
└── develop/
The actual worktree directory name is still `develop`, but the
worktree_id is unique and prevents the "take over" scenario. The suffix
is given by the `git_rand()` function, but I'm open to suggestions if
there's a better random or hashing function to use.
