We've gotten away with it so far because containers with varying width don't
come up all that often --- currently only when printing and authors use
@page rules to change the available width on particular pages, and there's
not a lot of need for that.

But with regions, we will have variable-width containers almost any time
regions are used.

I'm not saying it has to be in the Regions spec. It would make sense for the
changes to be in their own spec or distributed across other CSS3 modules
that update the spec of block-and-line etc.

I'm saying that if we start shipping implementations of Regions without a
spec for how variable-width containers work, we will have a big problem.
