original definition completely. (It also overrides lower-positioned
pieces of around-advice).
+If the around-advice uses @code{ad-do-it} more than once, the original
+definition is run at each place. In this way, around-advice can execute
+the original definition (and lower-positioned pieces of around-advice)
+several times. Another way to do that is by using @code{ad-do-it}
+inside of a loop.
