An edge case of note grouping

[Matthias Bry]

Hi all,

This is a question for those who have worked on the note grouping algorithm, especially on the use of "@".

Why is the third "@" in g@hg@h@jh necessary?

Looking at the doc, it looks as if g@hg@hjh (no third @) should render like g@hg@h@jh, not like ghg!hih as it currently does.

In Christo,

Matthias
