10.9 power button behavior

hi everybody!

with 10.9 the behavior of the power button has been changed and there is no option to get old behavior back.

(press once, get menu instead of press accidently and go to sleep without any questions...)

How to get old behavior back?

I try to figure it out, but failed... (plistbuddy, defaults, ...)

@Apple: Why in ... have you changed that? Any MS employees at Apple now? ...😟

Greetings,
