Incorrect $view parameter passed to hook_views_handler_options_alter()

Method views_handler::options_form() ends with:

    // Allow to alter the default values brought into the form.
    drupal_alter('views_handler_options', $this->options, $view);

However, at this point $view is not defined, and hook implementations just receive a NULL. Changing the code like this appears to bring the expected functionality:

options_form implementation.

    // Allow to alter the default values brought into the form.
    drupal_alter('views_handler_options', $this->options, $this->view);

Child handlers classed tend to be affected too because most (all ?) of them invoke parent::options_form() from the own
