beams in a two quarter bar

[Stefan Thomas]

Dear lilypond-users,
I have the following, I guess very simple problem, that I can't solve.
How can I get the beams in the below quoted example automatically?
Thanks for Your help
Stefan


\new Staff \relative { \time 2/4
c8 [ d e f ] g2 %this works, but it isn't automatic
 #(override-auto-beam-setting '(end * * 2 4) 4 8 'Score) %this
unfortunately doesn't help
c,8 d e f g2 }
