Ah, I suspected this might be so. I wonder if it would be possible to
alert the user if the \bar "" invitation to create a line break had
been taken up by LilyPond? If LilyPond issued some message then the use
would only need to examine those bars that had actually been broken to
tidy up (with the inevitable danger that the tidying up may cause the
line-breaking to change!).
Is there some hook-point where such a warning could be issued?
