    kern-tools: re-enable scc merge command
    
    The ability to merge two branches directly from a .scc file was
    dropped during the streamlining of the tools.
    
    As was pointed out by David Vincent <freesilicon gmail com>, there is
    once again a valid use case for this functionality, so we restore the
    capability.
