10.9: Disable new Power-Button Behavior

Hi

I think Mavericks is quite well, but there's one annoyance that is driving me nuts.
The new Power-button behavior.

I'm playing a game and hit the button accidentally. 20 Seconds until everything's back.

I'm writing in Adium and hit the button accidentally. It immediately logs me out of Adium.

Is there a way to bring back the old behavior (press the button and be asked what to do) or disable that button all together?

Yes I know, I can press 2 seconds and the dialog comes up, but that's not the issue. It's the "tap and you go to sleep" I don't like.
