Comment (by nacin):

 As users are allowed to have multiple roles, `role => array( role1, role2
 )` does seem confusing — is it an AND, or an OR? What if users have role1,
 role2, and *also* role 3? The patch assumes an OR, which might make sense
 if you are querying editor OR administrator, but not necessarily so for
 custom roles.

 I would think that AND is more obvious for an array passed to `role`. A
 `role__in` as an OR also fits similar patterns elsewhere, such as many
 vars in WP_Query.

 Sidenote: This going to be a fairly nasty meta query, at least until
 #10201 is ever tackled. If we do this API enhancement, let's not trumpet
 it too loudly. :-)
