@BurntSushi Have you considered providing a method for the 0th-always-OK group to make things clearer and avoid the .unwrap() in client code? Would have been helpful during review.

Haven't considered it, but it's not a bad idea! Thanks.

The `//[X]~` syntax filters errors for tests that are run across multiple cfgs with `// revisions:`. This commit extends that syntax to accept `//[X,Y]~`, which will match multiple cfgs to the same error annotation. This is functionally the same as writing two comments, `//[X]~` and `//[Y]~`, but can fit on a single line.
This test does not actually emit any warnings, since `#![allow(warnings)]` was specified. `compiletest` was erroneously ignoring `//~` tests and looking only for `//[X]~` ones. As a result of the changes in the previous commit, we now look for `//~` comments in incremental tests and expect them to appear in *all* revisions.

… r=Centril Support multiple revisions in `compiletest` The `//[X]~` syntax filters errors for tests that are run across multiple cfgs with `// revisions:`. This commit extends that syntax to accept `//[X,Y]~`, which will match multiple cfgs to the same error annotation. This is functionally the same as writing two comments, `//[X]~` and `//[Y]~`, but can fit on a single line. While refactoring `compiletest` to support this, I also uncovered a small bug that was causing an incremental test to always pass, despite no errors being emitted. r? @Centril
