I just tried that recipe, and with visual-line-mode (and line-move-visual) enabled C-e certainly doesn't behave how I'd expect. Rather than C-e moving to the end of the current visual line, if the current visual line wraps then it moves to the beginning of the next visual line. If I repeatedly press C-e, the cursor moves vertically down the first column of all those visual lines. Only the final visual line of the logical line will it move to the end. I'm seeing this in both 27.2 and GNU Emacs 28.0.90. Further testing indicates that the lack of any spaces in the wrapped visual lines is a factor. In a visual line with a space, the visual line will *end* with a space, and C-a will move to that. In this recipe there are no such spaces, and the problem arises. -Phil
