I don't know that - but I agree that it is confusing to the uninitiated
when in non-verbose mode. I'd make it conditional on verbose, and show
the error for the *last* address in the loop in any case.

Are you sure about the decades? At least the current loop through the
resolver results is the standard one recommended for protocol agnostic
applications recommended with the new IPv6-aware API, as far as I can
see.

I don't intend to remove the message but for the looping case as
long as we're not on the last address to be tried, and only for
the non-verbose case (-V). The default is verbose.

I have a diff ready, although only tested on netbsd-6.
