ACK.

Limited-width side-by-side comparators thank you for
splitting the long lines.

Thought note that we like continuation lines
to be aligned with the opening parenthesis, i.e.,

    VIR_DEBUG("dconn=%p, cookie=%p, cookielen=%p, uri_in=%s, uri_out=%p, "
              "flags=%lu, dname=%s, bandwidth=%lu", dconn, cookie, cookielen,
              NULLSTR(uri_in), uri_out, flags, NULLSTR(dname), bandwidth);

because that's what most automatic indenters do.
