Skip third party unsupported headers.

[idimopoulos]

We have a problem with some repositories when trying to parse the commit logs of the repository.
Apparently, come of the committers, are using third party tools (https://gitbutler.com/) which tampers with the log and adds additional metadata that might or might not exist before the commit message (might not = not committed with gitbutler).

I have added a method to skip lines until a new line is found in order to accommodate for this.

I have also provided a test (hashes and names are random but it is part of the logs we have encountered) that proves the problem.

Wo, I didn't know it was possible to do that. If there a public git with such header somewhere I can check?

@lyrixx sorry, I should have included that too. First time seeing this too. For us, the repository that had this is https://gitlab.opencode.de/open-code/badgebackend/badge-api
An example commit is https://gitlab.opencode.de/open-code/badgebackend/badge-api/-/commits/main?search=rename+docker-compose+to+compose

You can see it by cloning the repository I ran the following:

git clone https://gitlab.opencode.de/open-code/badgebackend/badge-api.git
cd badge-api
git log --pretty=format:%H | while read commit; do
  echo "=== $commit ==="
  git cat-file commit "$commit"
  echo
done

Search for the text "rename docker-compose to compose"
