For safety, "git worktree add <path>" will refuse to add a new
worktree at <path> if <path> is already associated with a worktree
entry, even if <path> is missing (for instance, has been deleted or
resides on non-mounted removable media or network share). The typical
way to re-create a worktree at <path> in such a situation is either to
prune all "broken" entries ("git worktree prune") or to selectively
remove the worktree entry manually ("git worktree remove <path>").
However, neither of these approaches ("prune" nor "remove") is
especially convenient, and they may be unsuitable for scripting when a
tool merely wants to re-use a worktree if it exists or create it from
scratch if it doesn't (much as a tool might use "mkdir -p" to re-use
or create a directory).
Therefore, teach 'add' to respect --force as a convenient way to
re-use a path already associated with a worktree entry if the path is
non-existent. For a locked worktree, require --force to be specified
twice.
