I think the crux of the matter is that the state in which we are at the beginning (when creating the *Completions* buffer) is unclear/accidental (is the first completion already selected or not?).


Exactly.


(when completions-highlight-face
  (setq-local cursor-face-highlight-nonselected-window t))

It's not clear to me how to "make this right", but maybe a "better ugly hack" is to work with the above `setq-local`, i.e. if `cursor-face-highlight-nonselected-window` is still nil (in which case, the cursor-face hilighting should be currently off), consider that `minibuffer-next-completion` should move to the *first* completion rather than to the next.


I thought about that solution, but what if someone sets completion-highlight-face to nil? I also tried to add another buffer-local variable to distinguish the first and later calls to minibuffer-next-completion, but that didn't work in all cases either.
