Thanks for your kindness! I would not "grab" this patch from you :)
I also worked locally on VincentWu's original patch and fixed some bugs on it, mostly the same as yours. I guess I can wait till you check-in this patch, then I can contribute on it such as bug fix and improvements. May I ask do you think if it's okay?
