Sorry, I was referring to that when I talked about facing-breaks (that
is, a page break across facing pages).  A facing-break comes between
column breaks and page breaks - it's more serious than a column break,
but less serious than a (general) page break.

In avoidance terms, you have, in increasing order of strictness: auto,
avoid-turn, avoid-page, avoid-column, avoid-all.  At the moment
avoid-all is identical with avoid-column, because there are only three
types of break opportunities we've current identified, and
avoid-column implies the other two, but it may in the future change.


(Man, I keep confusing myself by switching between avoid-* and allow-*
syntax.  When you include the concept of facing pages, avoid-page and
allow-page are *not* parallels.  In the allow-* syntax, the choices in
order are: auto, allow-page, allow-facing, allow-column, allow-none.
This time "auto" and "allow-page" are identical at the moment.  Let's
just stick to the avoid-* syntax.  It feels clearer.)
