Hmmm... no, the problematic cases also occur for example when the prompt 
and the initial input span multiple lines.  I'll send the recipe one more 
time:

(let (w bd)
  (setq w 60)
  (setq bd (concat (temporary-file-directory) (make-string w ?a) "/"))
  (dolist (d '("a" "b" "c" "d" "e")) (make-directory (concat bd d) t))
  (setq default-directory bd)
  (set-frame-height nil 20)
  (set-frame-width nil (+ (length bd) 10))
  (icomplete-mode)
  (setq icomplete-separator "\n")
  (call-interactively 'insert-file))
