Thanks for your answer, Trevor. I just tried with \stemUp and
\stemDown commands, and this indeed works for the example I gave.
But the trick fails if there are 1/8 notes. I join a slightly modified
example which shows the problem (the first line is using \stemUp in the
alto voice and doesn't look well, the second line looks well but uses my
cheating trick).

I'll now try to understand the partcombine discussion (I am a beginner,
you know)
