I was just about to edit my last comment to say that, yes, now I see it under Before You Fix Anything in your guide. I was just flipping back and forth between a dozen different pages, so I didn't see it earlier.

I assigned it to myself when I created it and didn't realize I had to change the status, so my bad on that, too.

hg qnew -f has created my patch, yay! So, sure, I'll patch these themes.
