Re: [musicxml2ly] beams and lost lyric syllables

[pls]

I forgot to mention that syllables don't get lost when musicxml2ly is used with 
the option --no-beaming.  But this is only a dirty workaround as LilyPonds' 
autobeaming algorithm overrides the beaming information provided by the 
.xml-file.  Beyond that we implemented a new musicxml2ly feature to translate 
the stem directions 
(https://github.com/Philomelos/lilypond-musicxml2ly-dev/commit/0747e5ce34f8d3a6128302ec0363a8f5f91ce3fd).
  This leads to ugly effects in combination with --no-beaming as LilyPond tries 
to connect notes with stems pointing in different directions...
