Re: install/57991: sysinst http/ftp download Host isn't clear about IPv6 address syntax

Oops -- wrapping in square brackets automatically doesn't work because
the Host field is the only place to put a port, so it really is the
user's responsibility to wrap in square brackets (since otherwise it
would be ambiguous with a port), which also isn't very clear.

Or, we could have a separate Port field.
