[css-lists] Almost all the spec is inside an example

[Loirooriol]

Example 2 is not closed, so the following spec contents are inside it.

The example just contains a description with no code, so not sure if it should be entirely removed, or if the code should be restored from before e1720ff

Ah, I meant to remove that example. Sorry about that. ^_^

(I really should put in that check for examples that have way too many children; this has happened several times.)
