Here's a test build if you'd like to help test before 0.3.9 is released.
(or if you'd rather get upgrading out of the way now instead of waiting)

Re: Version 0.3.9 rc1, please test
the extended-help might have been based on my idea, but the code was somewhat different.
The idea was the main part. When you posted your patch, I realized it should have been done that way instead of "-?". I always had reservations about "-?" because it intrudes on the possible parameter values, and the help response is based on the version of the caller instead of the server.
