Remove minibuffer message after appending to file

[Sebastien]

Is it possible to remove the text

"Added to <filename>"

which appears in the minibuffer after appending text to a file via

(append-to-file min max filename)
or
(write-region min max filename t)  ?


The souce code generating the message is in "fileio.c"  in the
function Fwrite_region .

  if (!auto_saving)
    message_with_string ((INTEGERP (append)
                          ? "Updated %s"
                          : ! NILP (append)
                          ? "Added to %s"
                          : "Wrote %s"),
                         visit_file, 1);

It would be nice to have a technique to bypass the message_with_string
function.
