title: Jest code coverage with wildcard path
body: <p>Is it possible to create a coverage report with jest for files that satisfy a wildcard path? After the latest release of jest, I can finally create coverage for files specified in the "collectCoverageOnlyFrom" config object (I'm on a Windows platform). I would however like to specify wildcarded paths, instead of every single file. Am I doing it wrong, or is it not possible?</p>

  <pre><code>"collectCoverageOnlyFrom": {
      "src/*.jsx": true,
      "src/**/*.jsx": true
  }
  </code></pre>
