The following is valid

  x(end-1, ...
    end-1)

as is

  if (cond)
    ...
  end, x(idx)

but probably neither is used much.  You also have to check for "}" and
I didn't notice before, but you'll have to do something with the uses of
octave-block-begin-or-end-regexp and octave-block-else-or-end-regexp.
