Shift no characters when using raw string literals Fixes rust-lang#104142 Given the following code: ```rust fn main() { println!(r#"\'\'\'\'\'\'\'\'\'\'\'\'\'\'}"#); } ``` The current output is: ``` error: invalid format string: unmatched `}` found --> src/main.rs:2:59 | 2 | println!(r#"\'\'\'\'\'\'\'\'\'\'\'\'\'\'}"#); //~ ERROR invalid format string: unmatched `}` found | ^ unmatched `}` in format string | = note: if you intended to print `}`, you can escape it using `}}` error: could not compile `debug_playground` due to previous error ``` The output should look like: ``` error: invalid format string: unmatched `}` found --> src/main.rs:2:45 | 2 | println!(r#"\'\'\'\'\'\'\'\'\'\'\'\'\'\'}"#); //~ ERROR invalid format string: unmatched `}` found | ^ unmatched `}` in format string | = note: if you intended to print `}`, you can escape it using `}}` error: could not compile `debug_playground` due to previous error ``` This pull request fixes the wrong span for `invalid format string` error and also solves the ICE.
