multiline string literal insert quotes after newline entered

Than edit c++ multiline string literals and insert new line, editor inserts quotes in the end of first and in the beggining of second line, just like it is ordinary string literal. For example

QString a = R"A(
dded<-Cursor is here, press newline
)A";

QString a = R"A(
dded"
"<-Сursor is now here
)A";
