Re: proposal: second style for quartertone accidentals

[Orm Finnendahl]

Hi all,

 thanks for pointing that out. That's exactly along the lines I was
thinking. Is anybody capable of doing the scheme/lilypond code? I
don't know Metafont yet but I think I could handle that part and throw
in the glyphs (they are currently PS Type1).
