Subject: Tk#array2tk_list bug?

Hi all,

If I have the following Array: ["a","","b"], then I suppose that the
tk-ized version should be "a {} b" instead of "a b".

Shouldn't the Tk#array2tk_list around tk.rb's line 202 should be
something like this?

  def array2tk_list(ary)
    ary.collect{|e|
      if e.kind_of? Array
	"{#{array2tk_list(e)}}"
      elsif e.kind_of? Hash
	"{#{e.to_a.collect{|ee| array2tk_list(ee)}.join(' ')}}"
      else
	s = _get_eval_string(e)
#	(s.index(/\s/))? "{#{s}}": s
# Instead:
	(s.index(/\s/) or s.size==0)? "{#{s}}": s
      end
    }.join(" ")
  end

Thanks,
Ferenc
