Formatting of the spec source

By the time I realized it was way too late down the road, but since we
are going to continue the work I was wondering if we should do some
reformatting of the master spec source.

The spec as it is has a surprising mixture of different indentation levels,
which makes it pretty frustrating to work with if you want to follow the
"surrounding conventions".

Right now, on ToT I see: (in spaces)
4
4 + 1
4 + 2
4 + 3
4 + 4 + 2
4 + 4 + 3

and the occasional \t, which is pretty messy. I can volunteer to clean this
up, as long as we find a consensus. (Markup format itself depends on
subjective preference, so let's push that discussion aside for now.)

I'm fine with the slightly more common 4 space indentation, the 2 space
indentation which a certain project seems to prefer, or 1 tab indentation.

We just need to make sure every contribution also follows the same style.

Poll? (I'll go ahead and put a vote on 4 spaces.)
