 Execute the var(list) associated with the first var(pattern)
 that matches var(word), if any.  The form of the patterns
 is the same as that used for filename generation.  See
 noderef(Filename Generation).

 If the var(list) that is executed is terminated with tt(;&) rather than
-tt(;;), the following list is also executed.  This continues until either
-a list is terminated with tt(;;) or the tt(esac) is reached.
+tt(;;), the following list is also executed.  The rule for
+the terminator of the following list tt(;;), tt(;&) or tt(;|) is
+applied unless the tt(esac) is reached.

+If the var(list) that is executed is terminated with tt(;|) the
+shell continues to scan the var(pattern)s looking for the next match,
+executing the corresponding var(list), and applying the rule for
