Yeah, I'll try to see if there's something I can do here, but it's going
to be largely guesswork. Here's the original email:

https://lore.kernel.org/lkml/22111b29e298f5f606130fcf4307bda99dbec089.1593077359.git.asml.silence@xxxxxxxxx/raw

The Fixes: footer really does get split into two. It's not that hard to
add logic just for the Fixes tag (since it conveniently follows a set
pattern), but finding a universal fix for split footers will be more
difficult.

I'll see what I can do.
