resolvconf -u generates "Too few arguments." errors

[Thomas Gschwind]

When adding new nameservers to /etc/resolvconf.conf (e.g., name_servers="8.8.4.4 8.8.8.8"), and running resolvconf -u, I get the following errors:
  prompt# resolvconf -u
  Too few arguments.
  Too few arguments.
  prompt#

At this time, /etc/resolv.conf has been updated and rerunning resolvconf -u does not generate the error again
  prompt# resolvconf -u
  prompt#

Only when /etc/resolvconf.conf is changed again, the above errors reappear.

As side comment, it would be nice to document the syntax for specifying multiple name servers in the resolvconf.conf. Thanks.

Indeed, same version as yours.

But it seems to work anyway.
It is just a irrelevant warning?
