Re: [csswg-drafts] [css-sizing] fill-available sizing should be clearer about margin collapsing

After discussion, fantasai and I think we can get away with just 
making the text simpler, and saying that for this purpose you should 
treat the margins as non-collapsing.  It's much simpler, has no effect
 in many layout modes (flex and grid items never collapse margins), 
and tho it can sometimes cause issues in block layout, they're usually
 avoidable.

An alternative is to assume that the element is *definitely* 
collapsing its margin with its parent (if the parent allows that); in 
other words, ignoring any possible intervening siblings.

Thoughts?
