arbitrary indentation. In fact, some might argue that the indentation rules
are *too* lax, but we'll let experience be the deciding factor on that.
Basically, here's the rules:
* a tab is 4 spaces. I considering not allowing tabs at all, but hopefully
people know not to mix spaces and tabs already.
* each line has its indentation level calculated
* a line is nested within the first line above it with a lower indentation
I actually think that sums things up completely. I have just added a page
on the documentation site to explain these rules, thank you for pointing out
that it was lacking.
