Is that correct, though? The reason we have *_printf_ln in the
first place is that we want to do:

  ${color}content${reset}\n

to make sure that the newline does not happen inside the colorization.
At least that is why I added color_printf_ln long ago.

It would probably improve the code quite a bit if we could simply feed
multi-line strings to status_printf, and have it stick the colorization
in the correct spot of each line. And hmm...it kind of looks like
status_vprintf already does that. Now I'm puzzled why many of these do
not simply include the newline along with the string being printed.

Hmm, yeah. It cannot be combined with the lines following it, either,
because they are using different colorization.

If you want to keep refactoring this, I don't mind, but I kind of feel
like we are going down a rabbit hole for very little gain.
