Hey, 

Correct, It should authenticate automatically

I think the issue is that some of the original sasl commit got lost in
cherry picking. I've attached a patch that fixes it, I'm not sure if
there is a better place to send a patch to a branch.

With this patch rcirc now checks that sasl authentication has completed
before running CAP END as specified here
