Conversation
Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @alexcrichton (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see the contribution instructions for more information. |
This looks great to me, thanks! It looks like some branch trickery on master caused this to now have some extra commits, could you rebase those out? After that I'll r+ and merge |

This little patch arises from the maelstrom of my purity born of pain. It's the pain of seeing rust-lang/rust#38103 in its perfect crystalline beauty waste away on page four of https://github.com/rust-lang/rust/pulls, waiting, ready, itching to land, dying with anticipation to bring the light of clearer lint group error messages to Rust users of all creeds and nations, only for its promise to be cruelly blocked by the fateful, hateful hand of circular dependency. For it is written in src/tools/cargotest/main.rs that the Cargo tests must pass before the PR can receive Appveyor's blessing, but the Cargo tests could not pass (because they depend on fine details of the output that the PR is meant to change), and the Cargo tests could not be changed (because updating the test expectation to match the proposed new compiler output, would fail with the current compiler). The Gordian knot is cut in the bowels of cargotest's very notion of comparison (of JSON objects) itself, by means of introducing a magic string literal `"{...}"`, which can server as a wildcard for any JSON sub-object. And so it will be for the children, and the children's children, and unto the 1.17.0 and 1.18.0 releases, that Cargo's build test expectations will faithfully expect the exact JSON output by Cargo itself, but the string literal `"{...}"` shall be a token upon the JSON output by rustc, and when I see `"{...}"`, I will pass over you, and the failure shall not be upon you. And this day shall be unto you for a memorial.
