As mentioned earlier, I'm not convinced S-RET is a great idea, since
I think it's more beneficial to get people to learn about C-q.

I do realize that we have a problem in C-q because you need C-q C-j
rather than C-q RET (the same problem recently pointed out by Raman
w.r.t to the ?\n in electric-indent-chars which affects the behavior of
RET rather than that of C-j).

So, S-RET is not without merit, but I'm still not quite convinced it's
a good idea.  I wish I could solve the "C-q RET doesn't insert
a newline" problem instead.

Good, please install it.

I'm less confident, but I think this is good as well.  Please install.
