It's not something I've ever advocated; I didn't realise there were so
many people unsetting it. (devtools does it for you)

The motivation for unsetting in in devtools is to avoid problems when
you run R CMD check from inside another R CMD check. I think it
affects some behaviour deep inside R, not just fancy quoting.
