Sounds sensible.

At this point we do not have "worktree list", but if we gained that,
we may want to add this as one more postcondition after the failed
"worktree add":

       git worktree list >actual &&
       ! grep precious actual

but that should happen in the series that adds "worktree list" ;-)
