Akim Demaille ea9e670d72 diagnostics: improve -fcaret for list of accepted values ...

Instead of

  input.y:1.9-21: error: invalid value for %define variable 'api.push-pull': 'neither'
   %define api.push_pull "neither"
           ^^^^^^^^^^^^^
  input.y:1.9-21:     accepted value: 'pull'
   %define api.push_pull "neither"
           ^^^^^^^^^^^^^
  input.y:1.9-21:     accepted value: 'push'
   %define api.push_pull "neither"
           ^^^^^^^^^^^^^
  input.y:1.9-21:     accepted value: 'both'
   %define api.push_pull "neither"
           ^^^^^^^^^^^^^
