How one can specify multiple name servers in each of the
following options in resolvconf.conf:  (note, it is not resolv.conf!)
https://www.freebsd.org/cgi/man.cgi?query=resolvconf.conf&sektion=5

append_nameservers
and
prepend_nameservers ?


Even though the options have "nameservers" in plural, I could not find any 
example anywhere on the net that would indicate multiple values for these two 
options.

I've tried
append_nameservers=127.0.0.1, 192.168.15.2
append_nameservers=127.0.0.1,192.168.15.2
append_nameservers=127.0.0.1 192.168.15.2
append_nameservers=127.0.0.1; 192.168.15.2
as well as specifying them on separate lines:
append_nameservers=127.0.0.1
append_nameservers=192.168.15.2

These different version yield 3 different outcomes, but none of them produces 
resolv.conf (upon running resolvconf -u) with both servers in there.

(Not that it matters, but there is an active information from dhcp 
server/client. Tested on 10.* system.)

I wonder if it is a bug...

Thank you in adavnce,

Igor
