The values of `title` and `nav_order` can be numbers or strings.
Jekyll gives build failures when sorting on mixtures of different types,
so numbers and strings need to be sorted separately.
Here, numbers are sorted by their values, and come before all strings.
An omitted `nav_order` value is equivalent to the page's `title` value
(except that a numerical `title` value is treated as a string).
The case-sensitivity of string sorting is determined by `site.nav_sort`.

{%- comment -%}
The nav_ordered_pages have to be added to number_ordered_pages and
string_ordered_pages, depending on the nav_order value.
The first character of the jsonify result is `"` only for strings.

The string_ordered_pages have to be sorted by nav_order, and otherwise title
(where appending the empty string to a numeric title converts it to a string).
After grouping them by those values, the groups are sorted, then the items
of each group are concatenated.
