A newbie isn't going to create a file with a newline in it; and the
others seem reasonable to me.

Maybe we could make an effort to quote as "a'b" instead of 'a'\''b', if
there are no ", $, or ` within a name, while still using '' quoting for
everything else.

But I _like_ quoting by default.  It's certainly nicer than representing
$'a\nb' as a?b, and having to guess what the glob expands to.

No, I don't think we should revert.  But I have no problem calling
attention to the fact that you can update your environment to select the
previous behavior as _your_ default, regardless of what we select for
the out-of-the-box default for someone that hasn't updated their initial
environment to request an alternate quoting mode.
