 To get informed when certain things happen in i3, clients can subscribe to
 events. Events consist of a name (like "workspace") and an event reply type
-(like I3_IPC_EVENT_WORKSPACE). The events sent by i3 are in the same format
-as replies to specific commands. However, the highest bit of the message type

+replies but with the highest bit of the message type set to 1 to indicate an
+event reply instead of a normal reply. Note that event types and reply types

 Caveat: As soon as you subscribe to an event, it is not guaranteed any longer

+If an event message needs to be sent and the socket is not writeable (write
