Thank you, @cpanato!

LGTM.
I'll see if I can resolve the conflicts from the GitHub Web UI, then we'll await a second LGTM before merging.

Hi @cpanato, it looks like I don't have permission to merge the changes to your PR. I think there is an "Allow maintainers to push to PR" or something like that if you want to try enabling it.

Otherwise, you are doing to have to resolve the conflicts yourself because the GitHub web editor doesn't appear to be working currently. Sorry about that.

The only change that's needed is to move your new custom header after the other new one:

diff --git a/github/github.go b/github/github.go
index bfe0453..d6b75ee 100644
