Chord compatibility problem

[craigsapp]

The secondary chord notes in Stage 2 files cannot be printed with muse2ps if the notehead shapes are missing.

Problem on the last chord:

measure 22
C3    96        w     u         S E
 C2                   u         S
mheavy2

The music will not print without adding a w to the C2 note:

measure 22
C3    96        w     u         S E
 C2             w     u         S
mheavy2

The data should either be fixed to add the rhythms or muse2ps should be adjusted to allow secondary notes in chords to not need rhythms (since they can take them from the primary note).
