changed method always returns true

[jonblack]

The changed? method returns true if and only if update_type is not equal to :no_change:

def changed?
  if update_type == :no_change
    false
  else
    true
  end
end

However, update_type can never be that value:

def update_type
  case raw_update_type
    when '<'
      :sent
    when '>'
      :recv
    when 'c'
      :change
    when 'h'
      :hard_link
    when '.'
      :no_update
    when '*'
      :message
  end
end

I suspect it should be if update_type == :no_update as :no_change appears to apply only to changes to attributes.
