Overwrites its equal operator

Updated Array#==

This modifies the original equality operator so that it returns true when both self and other are practically empty, that is, if #empty_element? and/or empty? are true for both, they are equal.

This modification is necessary because {Rangeary#empty?} never returns true; when it has no Range elements, it holds RangeExtd::NONE or equivalent, in whih case {Rangeary#empty_element?} returns true.

@param other [Object]

# File lib/rangeary.rb, line 1407
def ==(other)
  return true  if equals_before_rangeary other

  # It was false.  Is it?
  # eg., (Rangeary[RangeExtd::NONE] == []) is true,
  # because Rangeary[] with zero components does not exist!
  # Now either other or self is guranteed to be Rangeary.
  self_empt  = (respond_to?(:empty_element?) ? empty_element? : empty?)
  other_empt = (other.respond_to?(:empty_element?) ? other.empty_element? : other.empty?)
  self_empt && other_empt
end
