bug#48782: 28.0.50; fido-mode: shell variables distort find-file behaviour

[simon254--- via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

great, will do!

off topic:

would also be nice to have some simple helper functions to go to the first and last match in case of fido-vertical-mode, something along the lines of

(defun icomplete-vertical-last-completions ()
  "Go to last completions entry..."
  (interactive)
  (let* ((beg (icomplete--field-beg))
         (end (icomplete--field-end))
         (comps (completion-all-sorted-completions beg end))
         (last (last comps)))
    (while (consp (cdr comps))
      (push (pop comps) icomplete--scrolled-past)
      (setq icomplete--scrolled-completions comps)
      (completion--cache-all-sorted-completions beg end comps))))

(defun icomplete-vertical-first-completions ()
  "Go to first completions entry..."
  (interactive)
  (let* ((beg (icomplete--field-beg))
         (end (icomplete--field-end))
         (comps (completion-all-sorted-completions beg end))
	 last-but-one)
    (while icomplete--scrolled-past
           (push (pop icomplete--scrolled-past) comps)
           (setq icomplete--scrolled-completions comps))
    (completion--cache-all-sorted-completions beg end comps)))

But I don't know if changing this would be better or worse than the current behaviour after your fix - or possible at all.
