New issue 1507 by percival.music.ca: weird linebreaks in song output
http://code.google.com/p/lilypond/issues/detail?id=1507

The regtests:
  input/regression/song-reordering2.ly
  input/regression/song-reordering.ly
  input/regression/song-skip.ly
are constantly switching between hyphenated and non-hyphenated output:
-Ju
-ras
-sic
+Jurassic
 Park
-Ty
-ran
-no
-sau
-rus
+Tyrannosaurus
 Rex

I can't see anything obviously in the regtest that says "the output should  
change every time you compile this test", so this is a bug.  I suspect that  
there's an uninitialized variable somewhere.

Investigate, etc.  This isn't an important issue, but it's an annoyance for  
people looking at the regtests, and extra noise there makes it harder to  
spot actual problems.
