Test C++ code for formatting
1. $ clang-format -dump-config -style=LLVM | sed
's/\(MaxEmptyLinesToKeep\s*:\s*\).*/\10/g' > .clang-format
2. $ clang-format test.cpp
3. $ clang-format test.cpp | clang-format
4. $ clang-format test.cpp | clang-format | clang-format
5. $ clang-format test.cpp | clang-format | clang-format | clang-format
Notice how the output of #2 is identical to #4, while #3 is identical to #5,
and the difference between those two variants is the added/removed empty line
before 'private:'. That is this interleaving pattern of adding/removing this
empty line will repeat infinitely.</pre>
