Hello @cor3ntin
This patch has resulted in strings that were previously rejected are now
accepted by the compiler.
https://godbolt.org/z/c1jcGv76z
```
int main() {
(void) R"\t()\t";
(void) R"\f()\f";
(void) R"\n()\n";
(void) R"\v()\v";
}
```
My reasoning is that those strings should be rejected because the specification
says that the reverse solidus (`\`) is not allowed in the delimiter sequence.

Would you please check and fix if you agree with this analysis?
