open slur/tie at fragment end

[Antanas Budriūnas]

Hi LilyList,

finally I went back to music typesetting and am on a halfway of the
"sacred duty" – publishing a book about my grandfather and his
brothers (they all three were composers, choir conductors and
musicologists).
The first acquaintance with LaTeX went well. Especialy I'm grateful
for simple yet powerful approach using MAKE –

Only few problems remain not solved. One of those:
I didn't recall and can't find where recently I was reading about
trick for unfinished slur/tie at the end of music fragment.
The idea was somehow to hide the following system. It seems involves
\betweenLilyPondSystem or similar command.
Maybe you could point the right way?

Greetings

Antanas
