bug#3312: 23.0.93; Use punctuation syntax for apostrophe in Info

From my .emacs:

     (add-hook 'Info-mode-hook
               (lambda ()
                 (let ((st (copy-syntax-table text-mode-syntax-table)))
                   (modify-syntax-entry ?' "." st)
                   (set-syntax-table st))))

So this is a real problem for Info manuals.

AFAIK, the apostrophe has word syntax in text-mode to allow treating
word contractions as one word (can't, it's, I'll).  I don't know
whether this is grammatically correct or not but at least the Unicode says
that the category of the apostrophe is Punctuation, so perhaps we should
change apostrophe syntax to punctuation in text-mode as well.
