Print out ancient type stats with '~' prefix.

Browse Source 
The stale RR types are now printed with '#'.  This used to be the
prefix for RR types that were marked ancient, but commit
df50751585b64f72d93ad665abf0f485c8941a3b changed the meaning.  It is
probably better to keep '#' for stale RR types and introduce a new
prefix for reintroducing ancient type stat counters.
