Highlight error when regular expression contains hashes

It mistakenly treats all hashes as comment hashes. For example:

``` coffee
regex = ///
(/[^?#]*)? # path
///
```

Where the first hash should NOT be considered as a comment hash.


Reproduce the highlighting with the CoffeeScript regex example in the issue, then inspect the bundle's syntax-highlighting rule that classifies hashes as comments. Done means the hash inside the regular expression is not highlighted as a comment while the trailing path comment remains highlighted correctly.
