Thanks for the feedback, Matthew. You're right—the script was too 
aggressive for such a localized fix.

I used scripts/get_maintainer.pl without enough manual filtering. Are 
there specific parameters or workflows you recommend to keep the CC list 
lean for trivial cleanups like this?

I'll be more surgical with the CC list on the next version.

Thanks
Alex
