Two voices, only one note

[Alberto Simões]

Hi, Folks

I would like to mimic a score I have, where there are two voices in the
same score, but the note is used for both (instead of replicating it).

I am using this code:

                << { c8[ c'(-1 g c g c]) } \\ { c,2. } >>

And lilypond renders to notes for the first C. There is a common 
notation where the dotted minim is drawn with the beam down, and another 
beam up that is together with the other notes.

Is this possible?

Thanks for any help
Alberto
