No, in the current sources, it says:

  Here is an example of using these functions to reproduce Octave's
  command line.

  @example
  printf ("%s", program_name ());
  for i = 1:nargin
    arg_list = argv ();
    printf (" %s", address@hidden@});
  endfor
  printf ("\n");
  @end example

Please report bugs to the address@hidden list.

Also, please consider using an email address for the list that does
not require users to go to some web page and do something to be able
to send you mail.
