…nethercote Make `--print=check-cfg` output compatible `--check-cfg` arguments This PR changes significantly the output of the unstable `--print=check-cfg` option. Specifically it removes the ad-hoc resemblance with `--print=cfg` in order to output a simplified but still compatible `--check-cfg` arguments. The goal is to future proof the output of `--print=check-cfg` like `--check-cfg` is, and the best way to do that is to use it's syntax. This is particularly relevant for [RFC3905](rust-lang/rfcs#3905) which wants to introduce a new predicate: `version(...)`.
