Comment (by phercek):

 Actually instead of ":trace on/off" the interface should be rather ":set
 trace True/False". The reason is relationship of this ticket to ticket
 #2737. The rest stays as it is.

 One more advantage to this approach is that user can check whether tracing
 is on with ":show trace" (if it is implemented).
