Sorry, I missed that! Must have been a Joeclone at work, because Joe usually leaves a message when he edits.

Nope, it was Joe. I don't usually annotate fixed links or corrections of typographical errors, unless I see a teaching opportunity. I do make note when I add line breaks, because there's almost always a need for teaching there (and I have a ready-made note for that one).
