Glossary: incorrect 'incompl. dom. seventh chord' symbol

From: ArnoldTheresius
Subject: Glossary: incorrect 'incompl. dom. seventh chord' symbol
Date: Wed, 15 Aug 2012 23:48:23 -0700 (PDT)

In the section »functional harmony« of the music glossary
the symbol for the »incomplete dominant seventh chord« is
incorrect. It should be a »capital letter D with a diagonal
cancellation stroke, followed by a superscript digit 7«.

See the following patch diff file for my correction suggestion.

 It is based on the idea that, in a given key, there are only three
 functionally different chords: tonic (T, the chord on the first note of the
 scale), subdominant (S, the chord on the fourth note), and dominant (D, the
 chord on the fifth note).  Others are considered to be variants of the base
