+;; scrolling within Isearch mode. Alan Mackenzie (acm@muc.de), 2003/2/24
+;;
+;; The idea here is that certain vertical scrolling commands (like C-l
+;; `recenter') should be usable WITHIN Isearch mode. For a command to be
+;; suitable, it must NOT alter the buffer, swap to another buffer or frame,
+;; tamper with isearch's state, or move point. It is unacceptable for the
+;; search string to be scrolled out of the current window. If a command
+;; attempts this, we scroll the text back again.
+;;
+;; We implement this feature with a property called `isearch-scroll'.
+;; If a command's symbol has the value t for this property it is a
+;; scrolling command. The feature needs to be enabled by setting the
+;; customizable variable `isearch-allow-scroll' to a non-nil value.
+;;
+;; The universal argument commands (e.g. C-u) in simple.el are marked
+;; as scrolling commands, and isearch.el has been amended to allow
+;; prefix arguments to be passed through to scrolling commands. Thus
+;; M-0 C-l will scroll point to the top of the window.
