    ed: Move modflag=0 to clearundo()
    
    When we discard the content of an undo buffer
    is because we don't need it anymore, and it means
    that we don't care about the modify state of the buffer
    so we can reset the modflag in clearundo(), and
    remove this assignation each time clearundo() is called.
