Extended Description

$ echo -e 'void fu(void) {\ncout << "A" << "B" << "C" << D << "E" << "F" << "G"\n}' | clang-format -style="{BasedOnStyle: LLVM, AlignAfterOpenBracket: DontAlign, AlignOperands: false}"
void fu(void) {
cout << "A"
<< "B"
<< "C" << D << "E"
<< "F"
<< "G"
}

clang-format inserts an (unwanted) break before a lessless (stream insertion) operator if (and only if) it is between two string literals. Why? Is there any intention or rationale? (ColumnLimit cannot be a cause.)

Moreover the lessless-es get aligned, despite that no alignment is allowed.
