I didn't try it, but something like this should work: Move $iter to the
end of the line:

  do {
    $iter->forward_visible_word_end;
  } until ($iter->ends_line);

Get a copy and move it back one word:

  $reti = $iter->copy;
  $reti->backward_visible_word_start;

Get the text in between:

  warn $reti->get_visible_text ($iter);

If this doesn't work, try some other stuff from:
