I would have expected for-each-worktree-ref to iterate over all the
refs in a given worktree, but that is not what this does. This
instead iterates over worktrees and shows only their HEAD ref, no
other refs. This helper is somewhat misnamed.
By the way, doesn't nd/prune-in-worktree topic that has been cooking
in 'pu' supersede this change? It not just protects the commit at
the tip of HEAD in each worktree, it also makes sure the ones in
HEAD's reflog are not prematurely pruned.
Thanks.
