The order of sibling pages in `sorted_pages` determines the order of display of
links to them in lists of navigation links.

Note that Liquid evaluates conditions from right to left (and it does not allow
the use of parentheses). Some conditions are not so easy to express clearly...
-

For example, consider the following condition:
-
- C: page.collection = = include.key and
- page.url = = node.url or
- page.grand_parent = = node.title or
- page.parent = = node.title and

+ page.url = = node.url or
+ page.grand_parent = = node.title or
+ page.parent = = node.title and
page.grand_parent = = nil
-

Here, `node` is a first-level page. The last part of the condition
-- namely: `page.parent = = node.title and page.grand_parent = = nil` --
is evaluated first; it holds if and only if `page` is a child of `node`.
