It follows a precedent (made by me :p) which is rev-list
--single-worktree. I doubt that option is widely used though so we
could still rename it if there's a better name. I made
--single-worktree to contrast "all worktrees" by default. Even if it's
"this/current worktree" it still has to somehow say "everything in
this worktree" so I felt modifying --all was a good idea.

Of course. I was partly lazy/tired near the end, and anticipated more
comments anyway so I did not do it :D
