I was wondering why that series never made it to me turns out there's
some weird bug in my (neo)mutt where it sometimes marks messages as read
when I'm deleting completely unrelated messages. That has already cost
me a talk slot for an event I really wanted to attend and now it seems
to start costing me patches... I need to figure this out.

Anyway, thanks for sending this. I pulled this into my tree now.

Thanks!
Christian
