Resend: [PATCH] Do not log unless all connect() attempts fail

[Dave Zarzycki <zarzycki@apple.com>]

IPv6 hosts are often unreachable on the primarily IPv4 Internet and
therefore we shouldn't print an error if there are still other hosts we
can try to connect() to. This helps "git fetch --quiet" stay quiet.
