There's a problem here: the '?' key still does in Emacs what the
manual says it should.  So this is a discrepancy between the Emacs
Info reader and the stand-alone Info reader, and I'm not sure Emacs
should be the one which changes.

Why was '?' in the stand-alone reader bound to search-backward?  It
makes little sense to me, at least when in the default Emacs mode.  (I
notice that '?' has the same binding in the vi mode, perhaps someone
wanted to have the cake and eat it, too?)
