Comment (by ryan):

 Looking through core and a few plugins, most places use empty() or
 is_array() or (array) when dealing with the return value so they are safe
 with either array of false. One place does this though:

 {{{
 array_key_exists($blog_id, get_blogs_of_user($user_id)) )
 }}}

 Perhaps returning an empty array for both single and multi would be
 safest, as well as more semantic.
