[cfe-dev] Wrapping if and for body with brackets

[via cfe-dev]

Hi,
I want to wrap body of is statement inside a bracket.
Ex if()a=b; ---> if (){a=b}
I am doing with the help of
if(IfStmt *ifStmt = dyn_cast<IfStmt>(st)){
                rewriter.InsertTextBefore(ifStmt->getThen()->getLocStart(),"{\n");
                rewriter.InsertTextAfterToken(ifStmt->getThen()->getLocEnd(),";\n}//");
                if(ifStmt->getElse() != NULL){
                    rewriter.InsertTextBefore(ifStmt->getElseLoc(),"\n");
                    rewriter.InsertTextBefore(ifStmt->getElse()->getLocStart(),"{\n");
                    rewriter.InsertTextAfterToken(ifStmt->getElse()->getLocEnd(),";\n}//");
                }

But it is giving me weird answer like closing bracket missing or on
wrapping when if has single line body. Can someone inform me where I am
doing wrong.
