How to make commands non repeatable?

So instead of this:

=> print ipaddr
ipaddr=10.38.72.69
=>
ipaddr=10.38.72.69
=>
ipaddr=10.38.72.69
=>

To get:

=>
=> print ipaddr
ipaddr=10.38.72.69
=>
=>
=>
=>

Is there a better way of accomplishing this compared to the mod below:

-bash-4.2$ git diff
diff --git a/common/cli_hush.c b/common/cli_hush.c
index 296542f..2afa2de 100644
--- a/common/cli_hush.c
