do not confuse / after newline with regex

A division operator on a new line caused everything leading up to the next forward slash to be highlighted as a regex. 

```javascript
render: function() {
  var myRegex = /lol/;   //proper regex, all good
  var bucketWidth = superLongExpressionThatRequiresANewLineBecause80CharsLimit
    / data.buckets.length; /* "fake regex" */
  return (                 /* "fake regex" */
    <div />                /* "fake regex" */
  );
}
```
