bug#30077: 27.0.50; print-quoted should default to t

[Stefan Monnier <monnier@IRO.UMontreal.CA>]

Package: Emacs
Version: 27.0.50


I was reviewing some of my local patches and noticed that I tend to
let-bind print-quoted to t everywhere, and it occurred to me that
instead we should simply change the default.  I can't remember
a circumstance where I needed print-quoted to be nil (tho I wouldn't be
surprised if this patch ends up finding such a circumstance).

I suggest the patch below (for master, obviously).
