In case your user has long realname (15+ characters), such username will be trimmed to 15 characters and "..." added by default. If you wish to have displayed full name instead the trim version then place this code (D7) into your template.php:

/**
 * Overrides template_process_username().
 */
function THEMENAME_preprocess_username(&$variables) {
  $account = $variables['name_raw'];
  $variables['name'] = check_plain($account);
}

    'create form callback',
    'update callback',
    'update form callback',
    'delete callback',
    'charge callback',
