Sorry - I thought I had to add it to Documentation/snippets/new and 
run the makelsr.py script, rebuild the docs and then generate a patch?

It's a bit confusing. The ly file should be attached now. If not, 
there's something wrong with my mail.

Easy notation note heads use the @code{note-names} property
of the @code{notehead} object to determine what appears inside
the note head.  By overriding this property, it is possible
to print numbers representing the scale-degree.

A simple engraver can be created to do this for every notehead
object it sees.
