bug#23654: 24.5; wrong character syntax entry in emacs-lisp-mode

[ynyaaa@gmail.com]

Type C-h s to describe character syntax table in emacs-lisp-mode,
then *Help* buffer shows an strange entry.
	#x8A0		  	which means: whitespace
(the character is replaced by hex number)

It may be #xA0.
	#x8A0(ARABIC LETTER BEH WITH SMALL V BELOW)
	#xA0(NON-BREAKING SPACE)
