For stuff like the example where you know you will be reusing the command, it's better to use an alias or script. Even if it's just a command you plan to run in a couple times in a row you can add a temporay alias with: alias foo = "!!" - that way you don't have to hit ctrl+r each time.

Still, it's a good tip in terms of adding comments to unusual/confusing commands so when you go through your history you're not like "wtf was I doing here?" or if you unexpectedly need to recall it.
