Describe the bug
I'm using the jq library to format some JSON.

Here's what my markdown file looks like:

# Testing JSON formatting

```
~~~jq '.'
[{"q": "test"}]
~~~
```

Here's the command being run on the command line, to ensure it works as expected:

$ echo '[{"q": "test"}]' | jq '.'
[
  {
    "q": "test"
  }
]

Expected behavior
I'm expecting the code block to show the output of what I see when I run the command above in the command line.

I've verified that the file has chmod +x permissions and other commands work.

Screenshots
Just getting an empty code block. I've verified that the file has chmod +x permissions and other commands work.

I did some more testing and it seems that slides isn't happy with the quote (') in the command. Is there any workaround for this?

Are you able to remove the ' from the command?

# JQ

~~~jq .
[{"foo": "bar"}]
~~~

In this case dropping the quotes does work, thank you 🙂

Another "workaround" in the case where quotes might be necessary in someone's command for whatever reason: creating a script.sh file with the full command and then just calling that from the presentation *.md file.

# JQ

~~~sh script.sh
[{"foo": "bar"}]
~~~

and the created script.sh would look something like:

jq ".[0].q"

For syntax highlighting:

# JQ

```json
~~~jq .
[{"foo": "bar"}]
~~~
```

I think I know why the quotes do not work, as we have a similar problem with pipes: #148.

I think the solution can be that slides can make a temporary shell script file for the command and execute that if it contains quotes or pipes.

@maaslalani That sounds like an elegant solution! Thanks for this library, having lots of fun playing around with it.
