So Zeb's evil plan to break my mailing list script worked!
The moderately fragile bit that parses the patches relies on a regex matching '^From '. She included a comment in her code referencing another patch; a 'From <sha> here'.
That caused it to crash after sending 3 out of 4 emails, and before it marked that MR as done. So every time it woke up, it thought it needed to send that MR, would send 3, and then crash.
I have, in theory, mitigated that with this change: https://gitlab.winehq.org/winehq/tools/-/merge_requests/15
Sorry for the over flowing mailbox. Hopefully this patch set will get a *very* thorough review :-).
Cheers,
Jeremy
