It's not a bug, but a missing functionality. And no, it's not implemented 
in 0.7.1 yet.

Can you describe a scenario that you would like client to send CONFIRM?

In general, there are 2 cases (both are not supported yet):
1. client starts after crash/power outage and detects that is has still 
valid lease, so it sends CONFIRM instead of normal server discovery 

2. during operation, client detects that link went down and then up.
Then it sends confirm to verify if current address is valid.

Second scenario is quite difficult, because there's no general mechanism 
for detecting link up/down events. They're coded difrerently in Windows 
and Linux. So don't expect second scenario to be working anytime soon.

The first one is easier to do. But it requires some xml parser. And that 
in turn makes binary bigger. As I have fixed Dibbler port to some embedded 
environment (OpenWRT), that may be undesirable.

Anyway, I may be able to code scenario 1. Scenario 2 is planned for a 
rather distant future, unless someone is willing to help.
