Comment:

 I've got two methods to tackling this. (Well, 3, since one can be done in
 two ways...)

 1. Seperate functions. You can call is_page() to know if that page is the
 current page, and then also call is_page_child() to find out whether the
 current page is a child of X page. Also, is_page_descendant(). So,
 example:

 if (is_page(2) || is_page_child(21)) would return true if the current page
 is either ID 2, or a child of page 21.

 2. An argument to achieve the same as method 1. Either have a single
 is_page() argument that can be either what it is now (ID, page title,
 etc.), but can also be a query string so you can return true also if it's
 a child or descendant of another page. The other way of doing this is just
 having separate arguments.

 I'm torn.
