These functions were implementing the same stuff as empty messages functions provided by RedChannel so reuse them. The implementation seems a bit different but the result is the same. Specifically: - RedEmptyMsgPipeItem::msg is int while RedVerbItem::verb was uint16_t however this data goes into the message type which is uint16_t (a 16 bit on the network protocol); - red_channel_client_send_empty_msg calls red_channel_client_begin_send_message while red_marshall_verb does not. However red_marshall_verb is called only by cursor_channel_send_item and dcc_send_item which always calls red_channel_client_begin_send_message. Note that in dcc_send_item when an empty message is sent red_channel_client_send_message_pending always returns true; - when a PipeItem is created red_channel_client_pipe_add_empty_msg calls red_channel_client_push while red_pipe_add_verb does not. This actually make very little difference as this kind of item are never removed from the queue and a push is forced in every case running the event handler for the stream watch (see prepare_pipe_add and red_channel_client_event).
