It shouldn't be excluded because that pattern doesn't match any of the files.
If you run `git check-attr --all public/locales/foo/send.ftl` with the current .gitattr file, you'll get no attributes.
If you update the attr match to `public/locales/**` or `public/locales/**/*.ftl`, then the `check-attr` command above will match it and show 'linguist-documentation'.
