bug#3361: 23.0.92; View-scroll-page-forward/backward does wrong in text mode after text-scale-increase/decrease

[端瑞]

Open a normal text file with the text mode, do
(view-mode)
(text-scale-increase) or (text-scale-decrease)
(View-scroll-page-forward) or (View-scroll-page-backward)
The View-scroll-page-* command does wrong.  It cannot scroll "page
size" as expected like it does when the text-scale minor mode is off.
