    sh: Add case statement fallthrough (with ';&' instead of ';;').
    
    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.
