Replacing ;; with the new control operator ;& will cause the next list to be executed as well without checking its pattern, continuing until a list ends with ;; or until the end of the case statement. This is like omitting "break" in a C "switch" statement. The sequence ;& was formerly invalid. This feature is proposed for the next POSIX issue in Austin Group issue #449.
