Comment #3 on issue 1134 by address@hidden: Notes in different voices  
do not treat accidentals properly

Work-arounds, from discussion at  
<http://lists.gnu.org/archive/html/lilypond-user/2010-12/msg00434.html>.   
The output labeled 'human' looks very tidy in this particualar case, but  
breaks the usual horizontal-placement rule.
Output A or B would be safe and correct output for Lilypond, if she learns  
how to account for simultaneous pitches when determining accidentals.
