Correct. Since we introduced the globbing syntax long before I was aware of
the RFC2732 way of defining IPv6-addresses, we have a slight problem to
combine those two. I have not yet been able to come up with a nice fix to
allow both without it being a bit weird.

I guess we can fix it by more or less parse the IPv6 address in the client to
see if it is a glob or an address.

The amount of people using explicit IPv6-addresses like this in anything
but test purposes to see if curl deals with them, is probably less than a
handful. And they probably can live without globbing when doing so...

As you noted in your follow up, and as I honestly believe, libcurl does
resolve and use the given address correctly. (I've tried it myself on a few
simple address that I've made up on my IPv6-enabled linux, but I don't have
any IPv6-enabled servers! ;-O)
