Notation Reference bug

In "A.2 Common chord modifiers", the first entry in the table is wrong.

As noted in "2.7.1 Chord mode" under "Extended and altered chords", "as a special exception, `c:5` produces a ‘power chord’ only consisting of root and fifth". Thus the modifier column should contain only "nothing", the example column should just read "C1", and the output column should be updated by changing
   \chords{ c1:5 }
   \chordmode{ c1:5}
to
  \chords  { c1 }
  \chordmode { c1 }

As a further illustration of the problem, the second last row shows the "C1:5" notation being used correctly.

In addition, the output column for the last two entries should be modified to add the chord names:

In the second last row, change
  \chordmode {c1:5 }
to
  \chords { c1:5 }
  \chordmode { c1:5 }

and in the last row, change
  \chordmode {c1:5.8 }
to
  \chords { c1:5.8 }
  \chordmode { c1.:5.8 }

I hope this is useful,

Kevin.
