Subject: vnf: display also the break mark on report()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When reporting the final instruction, if that was actually a brk (and
hence we stopped because of it), show the breaking mark as that could be
relevant when debugging.
