Handle no values cfgs with `--print=check-cfg` This PR fix a bug with `--print=check-cfg`, where no values cfgs where not printed since we only printed cfgs that had at least one values. The representation I choose is `CFG=`, since it doesn't correspond to any valid config, it also IMO nicely complements the `values()` (to indicate no values). Representing the absence of value by the absence of the value. So for `cfg(feature, values())` we would print `feature=`. I also added the missing tracking issue number in the doc. r? ```@petrochenkov``` |

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).
