Running export-w3c-tests fails for me with a bunch of lint errors of the form 'file matches an ignore filter in .gitignore'. It seems that for some reason it ends up passing our new test files to `git check-ignore --stdin' such that the contents of the test file is interpreted as a list of files to check against the ignore list. Using the web-platform-tests directory as the CWD fixes this issue.
