 The author of the current post is the default user in the function
 `get_the_author_meta()`.

 `get_the_author_meta( 'display_name' )` will return the display name of
 the current global post's author. `get_the_author_meta( 'display_name',
 1260288 )` will return the display name of user 1260288 regardless of the
 post object.

 This quirk of WordPress allows developers to determine if the requested
 user data is for the current post or another purpose when using the
 [http://developer.wordpress.org/reference/hooks/get_the_author_field/
 get_the_author_{$field} filter].

 This behavior is not present in `get_author_posts_url()`, thereby making
 obtaining a filtering URLs of the current post's author more difficult.
 For the sake of consistency, it would be good to introduce the default
 value and match the pattern.

 This change would require adding the `$original_url` argument to the
 `author_link` filter.
