Formatting tweak
Alter `wp cron event run <hook>` so it fires the event inline instead of asynchronously
More comprehensive testing in `wp cron test`:

 * Displays an error if `DISABLE_WP_CRON` is set to true
 * Displays an error if the cron spawn fails
 * Displays a warning when `ALTERNATE_WP_CRON` is set to true
 * Displays a warning when the cron spawn request's HTTP status is something other than a 200
