Updated MANIFEST
Bumped version to 1.39_003; updated Changes notes (because I forgot to include Changes in _002)
Don't add t/multicall-refcount.t to MANIFEST
Nicer documentation style using only the function's name in =head2 with a preformatted synopsis afterwards; allows nicer cross-POD L<...> linking
Use L</foo> for internal linkage to mention other functions
