Some codes on master branch are not reformatted through `black`

When I follow the Contributing Guidelines to reformat my modifications, I found some codes on master branch have not been reformatted through black.
Here is the list of these files:

allennlp/data/dataset_readers/ccgbank.py
allennlp/data/dataset_readers/semantic_dependency_parsing.py
allennlp/data/tokenizers/pretrained_transformer_tokenizer.py
allennlp/models/coreference_resolution/coref.py
allennlp/modules/bimpm_matching.py
allennlp/modules/encoder_base.py
allennlp/modules/sampled_softmax_loss.py
allennlp/tests/common/test_util.py
allennlp/tests/training/callback_trainer_test.py
allennlp/tests/training/trainer_test.py
scripts/examine_sql_coverage.py

This is probably due to different black versions. I believe there is an open PR unpinning black; can you find it and comment there (on a phone so it’s hard for me to find it now)?

Yes–@jiyuanz is using a newer version of black than master. See https://github.com/allenai/allennlp/pull/3587
