Actually, it's just struck, me looking at key-engraver ...

Can I make chord-name-engraver respond to a key change to print the capo
indication? I don't know whether that's a good idea, or whether it would
even work, but it looks like it might be sensible...

But if it needs its own engraver, I think it's best for it to be my next
task, because once I've cracked Scheme enough to do that, I'll have
learnt enough to properly finish off the chord-name-engraver, before I
actually commit it to lilypond :-)
