bug#29806: 27.0; NEWS item about `electric-quote-replace-double'

[Drew Adams]

  ** The new user option 'electric-quote-replace-double' controls
  whether '"' is also replaced in 'electric-quote-mode'.  If non-nil,
  '"' is replaced by a double typographic quote.

Please say just what " is replaced by, and where (e.g. both start and
end quotes of "foobar"?).

Searching the Emacs and Elisp manuals for "typographic" turns up nothing
that would help a user understand what characters " gets replaced by.
