In outline mode, when C-c C-h is used to hide a section, that section does
not disappear immediately.  It does disappear when an ordinary character or
M-x is typed, or when C-l is typed.

I can demonstrate the problem by typing the following, starting at the
shell prompt.  My comments are in square brackets.

emacs -q <ret>
C-x C-f t e m p <ret>		[ Message "(new file)". ]
<esc> x o u t l i n e <ret>	[ Message "loading outline...done". ]
* <sp> s e c t i o n <ret>
* * <sp> s u b s e c t i o n <ret>
* * <sp> s u b s e c t i o n <ret>
* <sp> s e c t i o n <ret>
C-p C-p C-p			[ Cursor now on top line. ]
C-c C-h				[ The subsection lines should have disappeared,
				  but they are still visible. ]
C-b C-n C-f C-p			[ The cursor moves around, but the display
				  doesn't change. ]
x				[ Now the subsection lines disappear. ]

The problem also occurs with the C-c C-s command in outline mode, and also
affects a minor mode I cobbled together that uses selective-dislay.
