I'm not sure what you mean; can you write it out?

I actually wrote it that way first (I called it "maybe_add_color()"),
but it felt a little funny to have a separate function that people might
be tempted to reuse (the right solution is generally to check
want_color() early as above, but we can't do that here because we have
to find the end of each placeholder).
What I have here is a little funny, too, though, as it keeps trying
other color names if it finds "red" but want_color() returns 0.
