OK. So people have to learn how the group mask works anyway, and now
they have to learn a special exception to that rule.
I don't like having this exception. Or making the richacl->v4acl
translation dependent on the owner.
But I admit it's surprising to that an 0700 mask with
"bfields:rwx::allow" ACL denies access to a bfields-owned file.
