With our latest release of GNU "GNU Emacs 18.54.15 of  Mon Jun 19 1989
on deimos (berkeley-unix)" in outline mode when you do a 'show-subtree
nothing happens unless you do a 'recenter (^L).  I  tried to  fix this
with the following patch:


; Fix no activation after certain operations in outline mode.
(defun outline-flag-region (from to flag)
  "Hides or shows lines from FROM to TO, according to FLAG.
If FLAG is `\\n' (newline character) then text is shown,
while if FLAG is `\\^M' (control-M) the text is hidden."
  (let ((modp (buffer-modified-p)))
    (unwind-protect
        (subst-char-in-region from to
			      (if (= flag ?\n) ?\^M ?\n)
			      flag nil)  ; <--- was flag t in original
     (set-buffer-modified-p modp))))


But then loading outline mode files takes a very long time. Is there a
better patch?
