-The @code{save-restriction} special form records the values of the
-beginning and end of the accessible portion as distances from the
-beginning and end of the buffer.  In other words, it records the amount
-of inaccessible text before and after the accessible portion.

-This method yields correct results if @var{body} does further narrowing.
-However, @code{save-restriction} can become confused if the body widens
-and then makes changes outside the range of the saved narrowing.  When
-this is what you want to do, @code{save-restriction} is not the right
-tool for the job.  Here is what you must use instead:

-@example
-@group
-(let ((beg (point-min-marker))
-      (end (point-max-marker)))
-  (unwind-protect
-      (progn @var{body})
-    (save-excursion
-      (set-buffer (marker-buffer beg))
-      (narrow-to-region beg end))))
