Keeps column when goal-column is nil.

Looks like a bug.
No, it's a feature (assuming I understood what you are complaining
about; sorry if I didn't).


Thought at something like that:

(defun ar-previous-line (arg)
  "Moving ARG upwards.

Keep the column if possible. "
  (interactive "^p")
  (unless (bobp)
    (let ((col
       (if
           (eq last-command 'ar-previous-line)
           ar-vertical-move-start-column
         (setq ar-vertical-move-start-column (current-column)))))
      (previous-line arg arg)
      (when (< col (save-excursion (end-of-line) (current-column)))
    (move-to-column col)))))
