how to turn off automatic curly-quoting?

[Drew Adams]

I thought that the recent move to using curly quotes was
going to be optional for users.  But so far, it seems to
be hard-coded.  E.g., in `describe-function'.

I looked at NEWS, but I found only advertisements for the
touted new-&-improved behavior - nothing about how to get
back the classic one.

Oh, I did find `electric-quote-mode', which (sensibly) is
turned off by default.  But that apparently makes no
difference - I still see curly quotes substituted for
the longstanding, sane behavior.

Please tell us how a user can turn off this purportedly
optional curly-quote behavior - everywhere.

Oh, and please put this info in the Emacs manual, as well
as NEWS.  The only index entries for "curly quote" tell
you how to *insert* them, using (1) `C-x 8 RET' (`Inserting
Text') and (2) `electric-quote-mode' (`Quotation Marks').
