In a show-single-page case, the page from override dir should be shown anyway,
as it would be noticed first.

When showing any available pages (with or without the -w),
the override-vs-non-ov. order probably doesn't matter much.

Tagging as 'from-override' and sorting accordingly can be done,
but it would not be a simple incremental change.
