Upon realizing that I had written this but haven't used it in actual peco code other than testing, I tried it: It didn't work. Well, at least it didn't work out of the box. I could sense a loooooong debugging session ahead, and decided it's not worth it at this point in time. we can always re-instate it, as we have the history of it in git
