   In fact, the problem was due to documentation vagueness of

   updated in case `visit' is equal t. Nothing is said if `visit' is a

   when `visit' is not nil.

Do you really mean "always when `visit' is not nil" or do you mean
"when `visit' is t or a string":

If visit is neither t nor nil nor a string,
  that means do not display the "Wrote file" message.

   Is it worth a documentation clarification?

Probably it might be good to clarify the docstring and the Elisp
manual, as long as it really makes things more clear.

Docstring:

    Optional fifth argument VISIT if t means
      set the last-save-file-modtime of buffer to this file's modtime
      and mark buffer not modified.
    If VISIT is a string, it is a second file name; the output goes to
      FILENAME, but the buffer is marked as visiting VISIT.  VISIT is also
      the file name to lock and unlock for clash detection.

In the case of a string, one would have to specify which file's
modtime, because there is FILENAME and VISIT.  I guess the buffer also
gets marked not modified (I did not check).
