Update private ExitPolicy in man page and torrcs for 10727, formatting

Update the definition of the private exit policy in the man page
and torrcs. It didn't get merged correctly into the man page, and
it was incomplete in the torrcs. (Unfortunately, we only reject the
primary configured IPv4 and IPv6 addresses, not all configured IPv4
and IPv6 addresses.)

Also fixup msn page formatting errors from changes in tickets 16069
and 17027, mainly unescaped *s.
