Re: Unexpected white space at end of document if score in markup block (single page pdf output #ly:one-page-breaking)

Dear Lukas,

Brilliant -- that indeed does remove all the whitespace!

Should I file a bug for this issue?

And thank you for the feedback on the MWE -- I was thinking in comparison
to the code I had *written*, it was minimal. But that's not quite it!


Many thanks,
Matt
