wget should prefer IPv6 over IPv4

[Gioele Barabucci]

wget should prefer AAAA records over A a records when IPv6 connectivity is available.

To accomplish this the following line has to be added to /etc/wgetrc:

prefer-family = IPv6

With that setting wget will use AAAA records when available and use IPv4 as a fall-back.

[Davíð Steinn Geirsson (david-dsg)]

Confirmed in jaunty, the default is still to prefer A records.

Upstream Wget 1.12 has fixed this. It's in Debian unstable now, will probably find it's way to Ubuntu in Lucid Lynx.

Works as expected. Tested on Lucid Lynx.
