By default, outside-staff objects are placed without regard to
their horizontal distance from the previously-posititioned grobs. This
can lead to situations in which objects are placed very close to each
this example.

Note also that proportional notation in general takes up more
horizontal space that does classical spacing. Proportional spacing
provides rhythmic clarity at the expense of horizontal space.
