Thanks. I am always happy to see contributors willing to pick up and run
with ideas.

It is probably out-of-scope for what you want, but while we are talking
about %d, it may be worth considering whether there is something simple
we can do to make formatting list-like items more flexible. E.g., even
with "%D", you are stuck with the format "foo, bar, baz" for multiple
decorations. Some kind of "%join(%d,; )" might work to produce "foo;
bar; baz" (or whatever you want). But that may also be crossing the line
into insanity, and we would be better to allow some Turing-complete
embedded language like lua. For that matter, conditionals might be
crossing that insanity line, too.

Yeah, I agree it can be separate.
