OK.

Interesting.  However, if the dots' distances are not too far away
from the stem, the excellent Bärenreiter edition of the Bach Chaconne
*does* align them, even if they are in different voices.  Note that
this is a manually engraved edition from 1959 or so.

Yes, the result is better.

Yes, but much more annoying are situations as shown in the attached
image.  There's plenty of horizontal space between the stems to
properly put a dot inbetween, but the padding of stems and the dot
itself apparently prevents this.

Something different: I seem to recall that I've seen images sent to
`lilypond-user' or `lilypond-devel' which show coloured bounding boxes
of grobs.  However, I don't find related posts.  It would be great if
we could have a `-ddebug-bboxes' option which does that, possibly
providing options to include and exclude padding of grobs.
