Yes, that's good. I will change it.

OK, will change.

Either way is a little bit awkward, because these two subcommands share
4 out of 8 of their options. But since "delete" is really quite useless
to end users, I stuck its options in a separate section as you
suggested, but inline in a paragraph, where they won't bother anybody.

OK.
Thanks for your review! A reroll will be coming soon.
