Hi Stefan,

I noticed that you lowered the severity of this bug from "normal" to
"wishlist".  AIUI rcirc provides a way to automatically join channels
upon connecting to a server and currently this is not working as
intended, so IMHO it should be considered a bug instead of a feature
request (a wishlist).  (If you are using severity as a means to manage
bug triage priority I'm OK with that.)

Personally, as the patch is sufficiently trivial, I would hope it won't
take too much work for a review.  But I would understand if dealing with
rcirc-user-authenticated is more involved than it looks like and should
be handled with care.

Thanks!
