Summary: client -N "IPv6 address"

Initial Comment:
Seems -N option handling does not work correctly for IPv6 addresses.
The IPv6 address uses ":" as a delimiter. For example fe80::217:31ff:fe55:8d64 or ::1 (localhost).

And hpi clients tries to parse -N option as host:port so for ::1 we get NULL host and port 1 instead of ::1 host and default port.

Message:
OK.
We need to define syntax for -N option then. 
I see to ways to go:
A: clients can distinguish between IPv6 address and host:port.
This can be achieved by using the same syntax as IPv6 uses for URI:
[IPv6-address]:port
B: we change the options to only specify the host address in -N parameter
and have a separate paramter (e.g. -P) for port.

So in case of A, clients would assume anything between "[ ]" to be IPv6
address, and anything with more than one colon (":") to be IPv6 address. A
string with exactly one colon would be assumed an IPv4:port format.

In case of B, we would break compatibility.

Which way should we go?
