\noBeam causes the current beam to be removed entirely
and a new beam started at the next note.  If \noBeam is
placed on the last or next to last note in the beam group
then there is no place to start a new beam, of course.

The docs look to be misleading on this, but as the whole
beaming algorithm and documentation has been changed for
2.13.29 lets look at it again when that's out.

This is the easiest solution.
