That sounds good.

My initial reading was that Phil did not want to use @finalout (a
position which I entirely agree with).  I am not certain that we
have adequately investigated/discussed emergencystretch.

A quick google finds docs on emergencystretch, but I'm not certain
I understand them.  So I'll write an example and hope you can tell
me if LaTeX can do it.

----------- linewidth ------
This  is a  paragraph  which
is justified  like a  normal
paragraph in LaTeX.   It  is
unchanged by any  additional
TeX tweaking.

This  is a  paragraph  which
has  a really long  word and
has   benefitted  from  some
kind of
which  is IMHO  exactly what
we   want  in  the  lilypond
----------- linewidth ------

(must be viewed with a fixed-width font, of course)
