Repro:

int main() {
  double abcDEFghiJKLmno;  // Test comment
  int abcDEFghiJKL;  // This is a test of line wrapping. Line wrapping should
be idempotent.
}

First iteration:

int main() {
  double abcDEFghiJKLmno;  // Test comment
  int abcDEFghiJKL;        // This is a test of line wrapping. Line wrapping
should be
                           // idempotent.
}

Second iteration:

int main() {
  double abcDEFghiJKLmno;  // Test comment
  int abcDEFghiJKL;  // This is a test of line wrapping. Line wrapping should
be
                     // idempotent.
}

Output of "clang-format --version" (installed with "brew install
clang-format"):

clang-format version 5.0.0 (tags/google/stable/2017-03-17)
