Hi Urs,
This turned out to be a bit tricky, because stems and beams are strictly
coupled together in a way that the outer beams will always start/end at the
end of stems. And vice versa: Changes to beam positioning will always bring
along stem length changes.
Beam positioning with all the quanting issues (sit/straddle/hang...) doesn't
make it easier, either.
Therefore, the only solution I could come up with is to use parallel
contexts: one for the "ordinary" stems and another for the somewhat
squeezed-in-between knee-gap beam.
But, after all, you get away without having to define your own stencil :)
(1) ignore note collisions
(2) set auto-knee-gap to 0
(3) empty all the Stem details
(4) use crotchets for the "regular" stems, but scaled to semiquavers for the
right timing/spacing
(5) initiate a new new Voice for the parallel knee-gap-music to prevent
stems from being mixed up.
%%%%
{
\override NoteColumn.ignore-collision = ##t
\once\override Staff.Beam.auto-knee-gap = #0
\once\override Staff.Stem.details = #'()
<< { gis'4*1/4 e'' } \new Voice { gis'16[ e''] } >>
\revert NoteColumn.ignore-collision
}

Final adjustments to the beam could be made by using extra-offset.
HTH,
Torsten
