bug#50560: 28.0.50; 'insert-file-contents-literally' on multibyte buffer

I thought 'insert-file-contents-literally' literally just inserted the
file contents, as bytes, but I noticed that in the following code

    (create-image
     (with-temp-buffer
       (set-buffer-multibyte nil)
       (insert-file-contents-literally "picure.jpg")
       (buffer-substring-no-properties (point-min) (point-max)))
     nil t)

the call to 'set-buffer-multibyte' is really essential.

Is this intended?  If so, I think a note in the doctring is due.
