    Fixed infinite loop in verbose/debug message output.
    
    Setting the module/filename specific message level and then changing it
    resulted in the linked list being looped on itself.  Traversing this
    linked list is an infinite loop if what you are looking for is not in the
    list.
    
    Also plugged some CLI parsing holes in the associated CLI command:
    
    * Removing a nonexistent module from the list actually added it with a
    level of zero.
    
    * Setting the non-module specific level to zero is now equivalent to
    setting it to "off" as documented.
