arity warning when combining scopes with diffirent arity

[toy]

Post.published_or_user_id_is(user) works well (finds published posts or created by specified user), but warns:

lib/searchlogic/named_scopes/conditions.rb:115: warning: multiple values for a block parameter (0 for 1)
    from lib/searchlogic/named_scopes/conditions.rb:173

Is it reasonable to fix this? Or better add possibility to define scope like Post.published.or_user_id_is(user), as …_or_… assumes that parameters should be sent to both scopes.
