I hadn't looked at that code in a long time. The following is cleaned up 
a bit, and with a sample output at the end (you can see how it guesses 
that the last char is a delimiter of some kind).


class IRB::Context
   attr_accessor :max_output_size

   alias initialize_before_max_output_size initialize
   def initialize(*args)
     initialize_before_max_output_size(*args)
     @max_output_size = IRB.conf[:MAX_OUTPUT_SIZE] || 500
   end
end

class IRB::Irb
   def output_value
     text =
       if @context.inspect?
         sprintf @context.return_format, @context.last_value.inspect
       else
         sprintf @context.return_format, @context.last_value
       end
     max = @context.max_output_size
     if text.size < max
       puts text
     else
       puts text[0..max-1] + "..." + text[-2..-1]
     end
   end
end
