lib/Format/TokenAnnotator.cpp

if (Right.isTrailingComment())
     // list.
     return Left.BlockKind == BK_BracedInit ||
            (Left.is(TT_CtorInitializerColon) &&
             Style.BreakConstructorInitializers == FormatStyle::BCIS_AfterColon);
   if (Left.is(tok::question) && Right.is(tok::colon))
     return false;
   if (Right.is(TT_ConditionalExpr) || Right.is(tok::question))
