I fixed this in my tree, just didn't send a re-roll with it. I assumed
you will pull from there so you'd get the updated subject.

True.

I took a deeper look, and saving config should _in theory_ update the
in-memory state, and this indeed does happen for repo-specific settings
(which I unfortunately didn't test too well. Sorry). Changing global
settings is what is flawed.
I leave it up to you to decide if you want to pull the current patch. I
don't mind if you don't. I'll see if I can find some time to debug this
and send a proper fix.
Thanks for your input.
