does ancient music work correctly?

Does ancient music work correctly -- I mean `correctly' to the extent
of the limited support we have?  Looking at the headword of section
2.8 (Ancient notation), I see that the very last note clashes with the
final double barline.  Additionally, if I change the \paper section from

  \paper{
    ragged-right=##t
    line-width=17\cm
    indent=0\cm
  }

to

  \paper{
    line-width=15\cm
    indent=0\cm
  }

(this is what I would like to use to make it fit the page width of the
PDF, see attached image) I see that the \finalis double line is two
times positioned *before* the preceding note...
