Well, how to improve the following situation?
~~~
{
  \override Beam.after-line-breaking =
  #(lambda (grob)
    (format #t "\nbeam-positions:\n~y" (ly:grob-property grob 'positions))
    (format #t "\nbeam-segments:\n~y" (ly:grob-property grob 'beam-segments)))
  \stemUp
  a64[
    a
    a
    a16
    \stemDown
    c'''16
    c'''64
    c'''
    c'''
    c'''16
    \stemUp
    a16
    a64
    a
    a
    ]
}
~~~
Lily warns "may not find good beam slope". The overrides only return some 
info-values. Main-beam is the most left up beam-segment, the one with 
(vertical-count . 0)

I'm at a loss even to imagine how it _should_ look.

is this a bug or done on purpose? The following snippet produces beams
of which the lowest beam does not touch the staff line below.

The small-gaps-fill-with-ink theory should avoid this. IMHO the output
would look better like this:

~~~~
{
  \override Beam.positions = #'(2.7 . 2.7)
  g128[ g]
}
~~~~

What do the experts think?

This has been discussed at some length on the user list.
