Corrections to Wellons Emacs Chat.

I not only filled in the unclear xx spots, I combed through the first half of the video making small corrections (then ran out of time to continue).

First of all, this is a lot of work! Thanks for putting this crazy amount of effort into transcribing these chats. I was getting frustrated alt-tabbing back and forth between VLC and Emacs, trying to edit and follow what you've done without the video running away on me. It was enough of an annoyance that I decided to make a minor mode for controlling the video from the editing buffer. I used it for all my edits.

Maybe it will be useful for you for future transcriptions.
