Here are some samples.

This does not handle squeezing beams that are between two other
voices; in a way, such squeezing is wrong, as we have a minimum length
for stems, and the squeezing typically violates that length
constraint.  (I suspect that if you tune the minimum lengths down, it
already works.)
