All this stuff about Lucas being more involved in the script then I gave him credit for is stuff that I really didn't know. All I have to go on is the film's credits (which is all I should have to have to go on.) But honestly, I think Lucas' biggest contribution to the script was the story, which we do know he came up with. Kasdan did write the script, or else his name wouldn't be in the credits. (So did Leigh Bracket) But my point in my post is that Lucas had no right not to give credit to the screenwriters in the documentary. Lots and lots of fans will take their Star Wars history they repeat from that documentary, and its wrong to not mention people that did lots of work on the film.
