Hi NetBSD community,

Greetings from me!

Maybe a nitpick, but I think for su(1) manual: https://man.netbsd.org/su.1, we should mention it explicitly: "If both
login and group are not specified, ?root? is used."

If you think no need, just reject this issue, thanks! I posted this suggestion in netbsd-docs mailing list originally: https://mail-index.netbsd.org/netbsd-docs/2023/03/18/msg000643.html, but no one replied, so I reposted it here, sorry.

Best Regards
Nan Xiao
