## Changed


- (BREAKING) disallow multiple `doc` attributes in display impl
  [https://github.com/yaahc/displaydoc/pull/22]. Allowing and ignoring extra
  doc attributes made it too easy to accidentally create a broken display
  implementation with missing context without realizing it, this change turns
  that into a hard error and directs users towards block comments if multiple
  lines are needed.
