This is actually the whole point of this change - afaict I *can't* use
the existing chord name formatter. Because I've got TWO chords that I'm
trying to print as two chords but one markup.

But thanks for the pointer to clef-engraver - I'll investigate. And
thanks for the property stuff.

Here's hoping it all works :-)

I've now had a look at clef-engraver ... and I'm none the wiser :-(

What I need to do is:

chord-name-engraver creates, let's say, "C" as markup. I've added code that makes it *also* generate "A" as markup (but at the moment, it does nothing with it).

Now, instead of it returning "C" as it does at present, I want it to return "C (A)". I gather there's a function to parenthesize things? And then I need to stick them together, with a space between them, before returning the result.

Cheers,
