I'm having a bit of a struggle with the spacing of systems on the final page of a 12-page score. With \paper { ragged-last-bottom = ##t }
the final page has three systems crowded together, followed by a sea of whitespace, then the copyright line. But with \paper { ragged-last-bottom = ##f }
the spacing between systems is reasonable but the final system is too close to the copyright line.
I've tried various things, including:
changing the copyright line to \markup { \center-column { " " \vspace #10 "some text" }}
