I must be misunderstanding something... I thought that header was added automatically by #477? So I'm surprised there isn't a fix in this PR for that.

I'm fairly sure the license checking will need a series of bugfixes as we use it. For example, I'm looking at #475 and it's passing (on my local machine using an up to date upstream/master) despite the license headers not being updated. I'll raise an issue when I'm a bit more sure of what's going on.

Just spotted the issue. It's a logic error in the dictionary construction in #477. Apologies for missing it in the review. I'll submit a PR.

The header is not automatically added - it is simply checked that it exists and that the last commit year co-insides with the last year in the header. There is no first date checking.
