This patch doesn't seem to have landed in 1.9.2 and 1.9.3. Can someone backport it?

 Reproducing code:
 
   class Bug
     include Enumerable
     def each
       begin
         yield :foo
       ensure
         proc {}.call
       end
     end
   end
   e = Bug.new
   p e.detect{true}   # => :foo
   p e.any?{true}     # => true
   p e.all?{false}    # => false
   p e.include?(:foo) # => true
 
 All work expectedly if no Proc#call, but all occurs `unexpected break' with it.
