Whoops, make that:

      def parse_inline_styles(text) #:nodoc:
        segments = text.split( %r{(</?[ib]>)} ).delete_if{|x| x.empty? }
        segments.size == 1 ? segments.first : segments
      end

*Slaps head*.  I totally get what I was missing out on before, when
you use groupings, split includes the matched segments:

>> "kitten robot snake robot tree robot".split(/(robot)/)
=> ["kitten ", "robot", " snake ", "robot", " tree ", "robot"]
>> "kitten robot snake robot tree robot".split(/robot/)
=> ["kitten ", " snake ", " tree "]
