format_name replaced by theme('username', $node)

The changes in 4.7 included a getting rid of format name.
http://drupal.org/node/22218#theme_username

With the smarty engine for 4.7 (downloaded Jan 9, 2006) and drupal 4.7beta3 you get a blank page and the following error:

[client 127.0.0.1] PHP Fatal error:  Call to undefined function format_name() in /var/www/html/trizones2/themes/engines/smarty/smarty.engine on line 220

This only occurs on pages where the username is output. The patch changes all occurances of:
format_name($node) -> theme('username',$node)
