Is this on print excerpt or when you save as png? Print excerpt seems to
be broken for me for now. If I have time I will look into why that is
happening.

I got this from looking at the code when you click on an example at
lilypond.org. Every example defined something like:

#(define dump-extents #t)
  
  indent = 0\mm
  line-width = 160\mm - 2.0 * 0.4\in
  ragged-right = ##t
  force-assignment = #""
  line-width = #(- line-width (* mm  3.000000))

>From the manual ragged-right does this:

ragged-right
        
        If set to true, systems will not fill the line width. Instead,
        systems end at their natural horizontal length. Default: ##f.
        
        If the score has only one system, the default value is ##t.
        
I hope that helps.
