That's every users who wants cross-staff stems for chords.  Unless you
can come up with a better interface for dealing with cross-staff
stems, I'd rather you keep 'length for this case.

BTW, I had a head-scratching moment with the above override until I
realized that the begin/end-position callbacks return half-staff-space
values.
