But this is a change in how we match the error messages. Here is the text of the failure in #956:
```
AssertionError: Missing expected error: File not found 'feature/Modules/resources/no_such_file.js'
Actual errors:
Error: File not found 'd:\Projects\traceur\test\feature\Modules\resources\no_such_file.js'
```
Once we change the backslashes to forward, then `reDirectoryResources` matches (this much I verified). That is we already have error processing to convert the full path to a normalized name, it just was not working with backslashes. So the test should pass.

A slightly 'better' fix would change reDirectoryResources to handle backslashes but regexp with mixes of forward and backslashes are very hard to follwow.
