New issue 1470 by PhilEHolmes: Change keep-inside-line defaults to true
http://code.google.com/p/lilypond/issues/detail?id=1470

By default, PaperColumn #'keep-inside-line and NonMusicalPaperColumn  
#'keep-inside-line are both false, with the result that LilyPond allows  
text to disappear off the edge of the paper.  This is said to be in order  
to improve performance.  In practice, on a real-world score of 30 pages,  
performance is only improved by 0.2%, and even with a contrived score with  
30 pieces of text designed to overflow the page edge, performance is only  
9% better with the poor layout of the text.

The default should be changed so that good layout with a slight performance  
hit is the standard behaviour.  The learning manual will need changing at  
section 4.6.5 to mention a possible over-ride if performance is paramount.
