# (1) Whenever we do a PR we want pre-commit to run on all the files that have changed
# with respect to the branch we want to merge into. We don't want to compare to the file
# changes w.r.t. the last commit on the PR branch.
# (2) Whenever `github.event.before` is empty, it means we have hit the edge case where a
# branch does not yet contain any commits. This happens whenever a PR is created (GitHub
# creates a special PR merge branch) and the branch we want to merge did not have any
# commits yet. So this should fall under the `pull_request` case, but wanted to be
# explicit in case we want to make changes in the future.
# (3) If `github.event.before` is equal to a bunch of zeros, then we have hit another edge
# case. Triggered when a first push has been made to a new release branch. For this case
# we make use of the fact that we will always merge the release branch into master.
