bug in ActiveModel::StateMachine current state dynamic method with machine name is set

When we set name to state machine, dynamic method of current state falls.

Example:

class Example

include ActiveModel::StateMachine

state_machine :example do

state :new state :changed

event :change do

transitions :from => :new, :to => :changed

end

end end

p = Example.new

p.change!

p.current_state(:example) # => :changed

p.changed? # => :new

Why markup does not undesrtand new line ?
