It still can't handle link-local addresses:

$ curl -g 'http://[fe80::230:48ff:fe41:51d5%br0]/'
curl: (6) Could not resolve host: [fe80::230:48ff:fe41:51d5%br0]; Cannot allocate memory

Lynx and Elinks make the request OK but includes the '%br0' in the Host:
header, which lighttpd (at least) answers with "400 Bad Request".
Firefox works (it strips the %br0 from the address before putting it in
the Host: header).

It would appear that the CLI/terminal web client support for IPv6
link-local addresses is lacking.

I don't speak for anybody but myself - that's enough trouble.
