Any expert regexp wrangler around here. I can't quite find a way to split a 
document up in sections:

    This is an example.
        a = 1
    Of what I mean.
        b = 2

    And it can go on
    like this.

        c = 3
    For ever and ever.

        d = 4

    So how does one parse it?

I want to split it into groups, such that if in yaml it would be:

    ---
    - |
      This is an example.
          a = 1
    - |
      Of what I mean.
          b = 2

    - |
      And it can go on
      like this.

        c = 3
    - |
      For ever and ever.

        d = 4

    - |
      So how does one parse it?

I can write a line-by-line algorithm, but I figure there has to be an 
regexp that can do it more better.
