Subject: * enum.c (enum_each_entry): new method #each_entry to pack values  
 from yield into an array.

* lib/set.rb (Set#merge): use Enumerable#each_entry to implement
  Set compatible to 1.8 behavior.  [ruby-core:27985]

* lib/set.rb: replace is_a?(Enumerable) with respond_to?(:each)
  for duck typing.

* lib/set.rb (SortedSet#add): typo fixed.
