Re: Line breaks and text positioning

[Phil Holmes]

Thanks for the guidance.  I've tried adding:

\override PaperColumn #'keep-inside-line = ##t
\override NonMusicalPaperColumn #'keep-inside-line = ##t

and as you say it avoids the problem of text flowing over the edge of the 
page.  However, I am surprised that the default is to allow the overflow. 
On my tests, I can see no difference in processing time if those 2 lines are 
added - this is with a score taking about 25 seconds to process, and there's 
definitely less than a second difference.  Given that I can't think of any 
instance when the text should go over the side of the page, and the 
performance difference is negligible, could the default be changed?
