[Bug-wget] Possible bug with certain error messages being handled as non-error

[Christopher 'm4z' Holm]

Greetings!

First of all, thanks for maintaining this wonderful software that I've
been using for years without (code) problems.


Today however, I noticed wget behaving in a way that seems
counter-intuitive to me:
------------------------------------------------------------ 8<
------------------------------------------------------------
address@hidden:~> wget -t 1 --bind-address=123.123.123.123 www.google.com
--2015-09-02 15:33:17--  http://www.google.com/
Resolving www.google.com (www.google.com)... 2a00:1450:400f:805::2004,

argument.
Connecting to www.google.com (www.google.com)|216.58.209.100|:80...

Giving up.

address@hidden:~> wget -nv -t 1 --bind-address=123.123.123.123 www.google.com
address@hidden:~> echo $?
4
------------------------------------------------------------ >8
------------------------------------------------------------

(I'm deliberately trying to bind an IP that is not mine to provoke the error.)
According to the docs, "-nv" only suppresses non-errors. Are those
messages not considered errors?
