pre-push hook failed with "ValueError: too many values to unpack (expected 4)"

describe your issue

I ran

git push --dry-run origin HEAD^"{/^[a-zA-Z]+: }":refs/for/main%wip

and expected the hook to run properly, but it failed with a somewhat subtle error:

An unexpected error has occurred: ValueError: too many values to unpack (expected 4)
Check the log at $HOME/.cache/pre-commit/pre-commit.log

It was more clear from the pre-commit.log file, though (see below). I reproduced the issue using HEAD (f9473e7) as well.
