That is intentional behavior and has been that way (nearly) forever.  It 
is configured via the command definition macro on a per-command basis. 
"Dangerous" commands do *not* repeat, commands that may be useful to 
repeat (e.g. displaying memory) do.

Hey, you were just complaining that you had to retype the IP address for 
repeated pings - now you are complaining that you don't have to type 
anything to repeat a command.  Make up you mind if you want shortcuts or 
not!  :-P
