Note name to markup

[Hans Aberg]

Is there a way to print note names suitable for markup, in a transposable 
manner? - The idea is to print say "ef" as "E" followed by the flat used in the 
staff notation, as indicated by accidental alterations (so it also works with 
microtonal note names). The use I have in mind is when writing non-standard key 
signatures, and marking them with mode name and key - when transposing, it is 
easy to forget changing the markup key.
