Re: save-buffer in tar-mode

[Richard Stallman]

    I'd like to propose it again, i.e., make
    set-buffer-multibyte accept `to' as FLAG.
    (set-buffer-multibyte 'to) is exactly the same as:
    (let ((str (string-to-multibyte (buffer-string))))
       (erase-buffer)
       (set-buffer-multibyte t)
       (insert str))     

This approach is ok; it is simpler than what I proposed.
But this interface would be a kludge.  Please add a built-in
function with a new name to do this job.
