Now _I_ have been vague ... The code of write-region in fileio.c looks
like this:

  int visiting = (EQ (visit, Qt) || STRINGP (visit));
  ...
  if (visiting)
    current_buffer->modtime = st.st_mtime;

I've been lazy, my changed code in tramp-handle-write-region is:

      (when visit
	(set-visited-file-modtime))

Maybe I should go exactly to the behaviour as implemented in
write-region.
