I have a running copy of NTPsec with some changes. This interacts
with 000dfdcef, which I massively underdocumented. It complicated
the host name/address mode handling, abbreviated below.

```console
ntpq> help hostnames
function: specify whether hostnames or net numbers are printed
usage: hostnames [yes|no|hostname|hostnum]
ntpq> hostnames yes
resolved hostnames being shown
supplied hostnames not being shown
ntpq> peers

I don't suppose It'd be reasonable to change the default "hostnames
hostname" and change -n to "hostname hostnum"?  With corresponding
shifts of -s and -S to cover the "hostnames" values, yes and no,
respectively.

Altenatively, I have a couple of 2-line insert patches that:
- changes the t(ype) field to an arbitrary charaacter when the
  srcadr from mode 6 starts with '('
- changes the default displayed name to an arbitrary string
