Thanks for your contribution to Homebrew! Without people like you submitting PRs we couldn't run this project. You rock!

@MikeMcQuaid Gentle nudge that you forgot to mirror this one. Done now.

[MikeMcQuaid]

@DomT4 oops, cheers. An audit or something would be 🆒.

Checking mirrors aren't 404s generally is on my list. I'll try and squeak in a PR tonight if I can get the PR I've been working on (and frequently exasperated by) for the last couple days actually pushed for review this evening.

@DomT4 👍. Would be enough to check that a HEAD isn't a 404, I think.
