  SVN rev 211338 on 2010-08-15 14:55:32Z by des
  
  no-op commit to note that the example given in the previous commit is
  a very bad one, since the shift does not actually overflow.  This is
  a better example (assuming uint64_t = unsigned long long):
  
    ~0LLU >> 9             =   0x7fffffffffffffLLU
    ~0LLU >> 9 << 10       = 0xfffffffffffffc00LLU
    ~0LLU >> 9 << 10 >> 10 =   0x3fffffffffffffLLU
