This probably adds bullets all over the place, i.e. not only if there are multiple items. Try creating a task with no title, for example?

PHUIInfoView does this, which seems to be working:

if (count($errors) > 1) {
  $list = array();
  foreach ($errors as $error) {
    $list[] = phutil_tag(
      'li',
      array(),
      $error);
  }
  $list = phutil_tag(
    'ul',
    array(
      'class' => 'phui-info-view-list',
    ),
    $list);
} else if (count($errors) == 1) {
  $list = head($this->errors);
} else {
  $list = null;
}

I tried making the guidance show a single message and that looked right. Making a task with an empty title doesn't show the bullet either.

Oh, neat. I had no idea!
