bash code like $'\0' breaks syntax highlighting

[selivan]

Steps to reproduce

Public a page where bash code block contains $'\0'(bash-specific way to use string with escaped unprintable characters):

```bash
null=$'\0';
echo all further code is highlighted as string
```

Expected result

See correct highlighting: $'\0' is string, characters after closing ' are not.

Actual result

All further code is displayed as string until parser stumbles upon single quote ' character.

Additional information

Live site on github pages with this problem: selivan.github.io - ansible-check-on-commit-vault-files-are-encrypted.

First I contacted github-pages guys about this issue: github/pages-gem#436, they sent me to upstream.

Can you see if you can reproduce this using master? I think the github-pages folks might be on a super-ancient version.

@jneen yep, it's not reproduced with 2.1.0 version, ancient bug it is.

You mentioned(jekyll/jekyll#5919 (comment)), that you are getting a lot of issues for rouge 1.x. I suppose you can add an issue template(https://help.github.com/articles/creating-an-issue-template-for-your-repository/) to this repository, mentioning that. So jekyll users will stop bothering you and will start bothering jekyll guys to update to supported rouge version.

Haha yep, that would be helpful. I do hope they update soon!
