Prefer String.raw when backslashes are escaped only to preserve themselves

Repeatedly escaping literal backslashes obscures paths, regular-expression source, and similar text.
Instead, you SHOULD use a String.raw template when it preserves the same value without doubled backslashes.

Strings containing value-producing escapes remain unchanged.
