/* This is how unread counts work (and don't work):
 *
 * camel_folder_unread_message_count() only gives a correct answer if
 * the store is paying attention to the folder. (Some stores always
 * pay attention to all folders, but IMAP can only pay attention to
 * one folder at a time.) But it doesn't have any way to know when
 * it's lying, so it's only safe to call it when you know for sure
 * that the store is paying attention to the folder, such as when it's
 * just been created, or you get a folder_changed or message_changed
 * signal on it.
 *
 * camel_store_get_folder_info() always gives correct answers for the
 * folders it checks, but it can also return -1 for a folder, meaning
 * it didn't check, and so you should stick with your previous answer.
 *
 * update_1folder is called from three places: with info != NULL when
 * the folder is created (or get_folder_info), with info == NULL when
 * a folder changed event is emitted.
 *
 * So if info is NULL, camel_folder_unread_message_count is correct,
 * and if it's not NULL and its unread_message_count isn't -1, then
 * it's correct.  */
