doesn't respect .eslintignore

Can you reproduce the problem with latest npm?

yes

Description

create-react-app 1.x doesn’t respect .eslintignore. (It was use to respect it on version 0.9.x).

Expected behavior

Not showing ESLint warning/errors of files in the .eslintignore file

Actual behavior

See warning such as:

Compiled with warnings.

./src/vendor/modernizr.js
  Line 25:   Shadowing of global property 'undefined'     no-shadow-restricted-names
  Line 163:  Do not use Boolean as a constructor          no-new-wrappers
  Line 431:  Unexpected string concatenation of literals  no-useless-concat
  Line 436:  Expected '===' and instead saw '=='          eqeqeq

Search for the keywords to learn more about each warning.
To ignore, add // eslint-disable-next-line to the line before.

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts (if you haven’t ejected): react-scripts@1.0.5
2. node -v: v6.10.0
3. yarn -v: v0.24.5

Then, specify:

1. Operating system: OSX Sierra
2. Browser and version: *

Reproducible Demo

.eslintignore :

vendor/*.js
src/vendor/*.js
src/vendor/vendor.js

src/vendor.js:

(function(undefined) {
  var a = 1;
  var b = a == 1;
  window.$someProp$ = b;
}());

src/index.js:

import "./vendor/vendor.js";

[Timer]

CRA 1.x+ purposely does not support .eslintignore. Sorry!

Please move vendor files into public/ or use a NPM package.

really need .eslintignore for *_pb.js produced by protobuf, is there some workaround now?
