Recipients are not counted

Recipients are not counted in forward module because of a mistype.

Version of forward.module:
/* $Id: forward.module,v 1.11.2.5 2006/03/27 21:59:18 seanr Exp $ */

Line with error
575: variable_set('forward_recipients', variable_get('forward_recipients', 0) + count($recipient_addresses));

There is no $recipient_addresses variable but $recipients.

Below code will count "," comma characters in recipients list and add 1.
variable_set('forward_recipients', variable_get('forward_recipients', 0) + substr_count($recipients, ",") + 1);

Same problem exists also in /* $Id: forward.module,v 1.11 2006/03/10 00:24:03 seanr Exp $ */. This version seems to be in CVS but it is older than forward module 4.7. This time problem is in line 568.
