Nice, this now uses a strbuf as recommended.

And this prints into the buffer diretcly. Makes sense.

Let's declare the strbuf outside of the loop and `strbuf_reset()` it on
every iteration.

I don't think we should explicitly initialize it with a specific
capacity. Let's just use `STRBUF_INIT`.

And the call to `strbuf_release()` should be moved to the end of this
function so that we know to reuse the buffer. The above early return
would then be converted into a `goto out` so that we have a common exit
path where we know to clean up all resources.
