pipewire pacnew files
I saw I got these pacnew files when upgrading, but I can't recall modifying the originals? It's not impossible I could have done and forgot I suppose, but I think this only got installed on my OS as a dep or build dep of something else and I couldn't see anything searching .bash_history. Reinstalling the last pipewire version from my cache still had the pacnew's so it's been like that a while.
