 3.4 fixed canonical redirection for singular pagination, see #20385 and
 [20397].

 However, some users were using the "page" query parameter for something
 other than WordPress' default pagination. The canonical redirect hijacks
 this even if the post/page is not multipaged.

 An example is buddypress.org: http://buddypress.org/extend/plugins/?page=2

 This can be fixed by those relying on the broken redirect. Instead of
 looking for `$_GET['page']` retrieving the value from $wp_query can be
 done: `get_query_var('page')`. Using that it should work and give pretty
 URLs.
