As Will Oram pointed out, there are problems when \break occur near grace notes.
In this example, the second but not the first score does a line break: \version "2.3.11" A = \new Staff \notes {c1 | \grace c8 c1 } B = \new Staff \notes {c1 | \break c1 } \book { \score {<<\A \B>>} \score {\B} } I consider this a bug. I have been thinking about how it best would be solved. My conclusion is that the cleanest way would be to add a timestep that happens right before all grace note timing. I.e. in the case c1 | \break \grace c8 d1 the c1 would be at time 0 in the first bar, the \break at the new time 0-inf in the second bar, the c8 at time 0-1/8, and the d1 at time 0 in the second bar. Another possibility (which I however don't find as clean) is to let the \break command search for grace notes in all other staves, and move itself to a spot right before them. Any opinions, developers? I'll add this as a bug if you don't protest.
