ChordGrid and chordNameExceptions

[Eric Benson]

I started experimenting with LilyPond's ChordGrid display. I can't find
very many examples using it, so I guess it isn't very popular yet. I'm
using Brandt and Roemer chord names instead of the built-in Ignatzek chord
names, using chordNameExceptions for that purpose. It looks like ChordGrid
doesn't follow chordNameExceptions. Am I doing something wrong, or is that
intentional? Is there another way to supply my own chord names in the
ChordGrid context?
