Arrowed quartertones notes snippet compilation problem

[Jacques Menu]

Hello folks,

The snippet at http://lsr.di.unimi.it/LSR/Snippet?id=784 leads to the error 
messages below with LP 2.19.83.

Didn’t find eiseh nor feh in Lily's source code.
I don’t know which version it was written for. Does anyone know?

Thanks!

JM
