- Previously this only included the formula name.
- But, for example in tests, we have "#{bin}/ansible-test",
not just "#{bin}/ansible". So handle that too.
- I decided to make the error message better by extracting the
binary name from the interpolation, but I'm not sure it was worth it.
```
$ brew audit --strict ansible
ansible
* line 580, col 29: Use `bin/"ansible-test"` instead of `"#{bin}/ansible-test"`
Error: 1 problem in 1 formula detected.
