Details:

It seems the output is wrong.
the example
++
strtchunk = "[ONE]\n1\n[TWO]\n2\n";
[S, E, TE, M, T, NM, SP] = regexp (strchunk, '[\[]{1}(\w+)[\]\n]{1}');
--

shouldn't it provide aligned T and SP, but SP always has an empty at the
beginning

++
octave> T
T = 
{
  [1,1] = 
  {
    [1,1] = ONE
  }
  [1,2] = 
  {
    [1,1] = TWO
  }
}
octave> SP
SP = 
{
  [1,1] = 
  [1,2] = 
1

  [1,3] = 
2

}
