What I mean is that if something like

{
\override NoteHead #'style = #'kievan
c'8
}

produces a quarter note in the output, the user is likely to be
thoroughly confused.

If NoteHead and Stem properties are set up in engraver-init.ly, then if
the user wants a Kievan NoteHead somewhere other than in a KievanVoice
context, he will need to set up other overrides in addition to NoteHead
style.

This is different from other ancient notations in the sense that if I
do, e.g.,
{
\override NoteHead #'style = #'mensural
}

things work as expected. Of course, Mensural notation is simpler in the
sense that it lacks beams and specialized eighth heads.

I think it would be best if setting NoteHead style to Kievan would set
the necessary duration-log and Stem properties, but I am not sure how
that would be implemented given the clean-ups that Mike is proposing
with this patch.
