[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] Re: #4048 Is Dynamic_performer’s understanding of (de)crescendo too limited?

[Auto mailings of changes to Lily Issues]

mid-crescendo dynamics
e.g. << { c'1\< c' c'\! } { s1 s\p s } >>

On second thought, this is not a case that needs to be handled. In my test file, I didn't force the simultaneous music into the same voice, so what looked like mid-crescendo dynamics to me was just parallel voices. An absolute dynamic ends a crescendo or decrescendo in a voice, so only the cases with dynamics at the start and end need to be handled.
