browserslist file doesn't support comments

See original GitHub issue

Hey there, when I add a comment to the top of my browserslist file, I get the error:

BrowserslistError: Unknown browser query `# TODO: [my comment]`
    at error (/home/site/node_modules/browserslist/index.js:37:11)
    at /home/site/node_modules/browserslist/index.js:222:9
    at Array.forEach (native)
    at browserslist (/home/site/node_modules/browserslist/index.js:196:13)
    at new BrowserSelection (/home/site/node_modules/doiuse/lib/browsers.js:17:18)
    at missing (/home/site/node_modules/doiuse/lib/missing-support.js:76:18)
    at doiuse (/home/site/node_modules/doiuse/lib/doiuse.js:42:25)

    at Promise.resolve.then (/home/site/node_modules/stylelint/lib/lintSource.js:122:52)

This was surprising considering the example in the README:

# Browsers that we support

> 1%
Last 2 versions
IE 10 # sorry

I’m using browserslist 1.7.7.

I found problem — doiuse uses Browserslist in completely wrong way. I created a issue to fix it: https://github.com/anandthakker/doiuse/issues/67

Thanks for waiting 😃.

Hi @ai, check out https://github.com/ch2ch3/browserslist-comments. Run npm install && npm run lint:css and you should see the issue. I’ve added the debug log to the repository as well.
