Don't try to access files that should be ignored.

[purpleKarrot]

I have some files that cannot be accessed by the current user. Even though I have listed them in both ".gitignore" and "standard.ignore", I get the following output:

> standard --verbose | snazzy

standard: Unexpected linter output:

Error: EACCES: permission denied, scandir '...'

This happens with raw eslint, so it's not something that standard is doing. See:

$ ls -lha t.js
-rw-------  1 root  wheel    19B Jan 12 21:57 t.js
$ ./node_modules/.bin/eslint -c eslintrc.json .

I suggest fixing the permission issue with the file, or if you feel strongly, open an issue on the ESLint bug tracker here: https://github.com/eslint/eslint/issues
