Dear Klaus;

Many thanks for this proposal. It is ever better to use 'official' functions.

I've just tried to test your version. But it does not work, because my LilyPond
version 2.18.2, offered by Ubuntu 19.10, does not contain a function \overlay. I
have the hope, that the coming LTS Ubuntu version 20.04 will contain the newer 
2.19.x  - LilyPond. 

But I have copied your new version into the source code as an out commented
snippet and will publish it together with the next harmonyli.ly version. So, you
should be able to test it easily.

wbole-heartedly Karsten
