Polyphony

[Tomas Valusek]

Hello,

the last example in section 6.6.2 of the User Manual shows how tu have 
three-voice part with the upper voice slurred. But what if I need the 
last half notes appear as a single chord, not as a gathering of three 
voices with three stems? It seems to be quite common in music I'm trying 
to type into LilyPond.

Thanks for any help.
