no, if you use chordNameExtensions, the name of chord root is
not affected with your text markup, only the chord "modifiers".
you still have to use \chordmode so you can also transpose chords
and play them in the midi file.

see "chord-name-exceptions.ly" in the regression tests, and change
the root of the chords inside theMusic block to e.g "d:7sus4" instead of
"c:7sus4". then you'll see D7wahh at the output :)

although it may be a bit misleading, in:

chExceptionMusic = {
    <c f g bes>1-\markup { \super "7" "wahh" }}

<c f g bes> is not implicitly related to the "c" based chord, but
to the relative intervals inside the chord, in this case to all the
7sus4 chords, regardless of the root.
