I'm not sure I get what you are trying to tell me. Do you want the unit test to 
be the minimal reproducer of the error?

As far as I have tested the changes work, these are some unit tests I have done 
(but not commited) to check it:
```
{
  auto Style = getLLVMStyleWithColumns(60);
  Style.BreakBeforeBinaryOperators = FormatStyle::BOS_NonAssignment;

  Style.BreakBinaryOperations = FormatStyle::BBO_OnePerLine;

  verifyFormat("std::cin\n"
               "    >> longOperand_1\n"
               "    >> longOperand_2\n"
               "    >> longOperand_3_;",
               Style);

  verifyFormat("std::cin >> longOperand_1 >> longOperand_2 >> longOperand_3;",
               Style);

  Style.BreakBinaryOperations = FormatStyle::BBO_RespectPrecedence;
  verifyFormat("std::cin\n"
               "    >> longOperand_1\n"
               "    >> longOperand_2\n"
               "    >> longOperand_3_;",
               Style);

  verifyFormat("std::cin >> longOperand_1 >> longOperand_2 >> longOperand_3;",
               Style);
}
```
