On a site this is a plugin that uses
get_pages() to make a list of pages. The list is used to create a list of pages and create next page and previous page links. ( http://wordpress.org/plugins/next-page-not-next-post/ )
The structure of pages uses some empty pages just to make a hierarchy. Those pages are not in the navigation, which is controlled by
wp_nav_menu(), but they are enlisted when the plugin calls
So I want to remove those empty pages from the request made by the plugin.
My intent is to add a custom field to each unnecessary page, and to use this custom field to select and remove them.

But it's a deadhead since the
get_pages() launched by the plugin is not the main query.

get_pages(). I want to change the behavior of this plugin without hacking its core. So I figured that I could change the
get_pages()output, because it will change the output of the plugin. Doing so, I find how to filter
get_pages(), and this is my solution below for documentation, but I also find out that the plugins uses two other functions that I cannot bypass or filter, so my attempt for this particular case is a dead-end.
