Well, yeah, if we want to replace (not hide), only,
as always, the byte compiler is your friend!

  In cut-ctrlM:
  [...]Warning: ‘beginning-of-buffer’ is for interactive use only; use
      ‘(goto-char (point-min))’ instead.
  [...]Warning: ‘not-modified’ is for interactive use only; use
      ‘set-buffer-modified-p’ instead.
  [...]Warning: ‘beginning-of-buffer’ is for interactive use only; use
      ‘(goto-char (point-min))’ instead.

And... maybe wrap it in `save-excursion' as well?
