Comment(by nacin):

 With this we can probably remove an isset() check or two later in the
 file.

 Also, it looks like we check for !empty() for wp_ajax_nopriv_ but only
 isset() for wp_ajax_. Standardizing this on !empty() up top would be good.
 I don't see a reason for firing the literal hook "wp_ajax_" if admin-
 ajax.php?action is called.
