Based on the environment variables, I was expecting PRE_COMMIT_TO_REF to be 0000000000000000000000000000000000000000 here, in the case of a ref deletion.

Would you propose an alternate wording, or not documenting this at all?

environment variables:
- `PRE_COMMIT_FROM_REF`: the revision that is being pushed to.
- `PRE_COMMIT_TO_REF`: the local revision that is being pushed to the remote.
