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?
