Fix substitution parts having a shifted underline in some cases If two suggestions parts are side by side, the underline's offset: (WIP PR as an example, not yet pushed) ``` error: expected a pattern, found an expression --> ./main.rs:4:9 | 4 | 1 + 2 => 3 | ^^^^^ arbitrary expressions are not allowed in patterns | help: check the value in an arm guard | 4 | n if n == 1 + 2 => 3 | ~ +++++++++++++ ``` The emitter didn't take into account that the string had shrunk/grown if two substitution parts were side-by-side (surprisingly, there was only one case in the ui testsuite.) ``` help: check the value in an arm guard | 4 | n if n == 1 + 2 => 3 | ~ +++++++++++++ ``` ``@rustbot`` label +A-suggestion-diagnostics |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
