support expanding code blocks

[juhp]

Just found this interesting project, thanks. It seems close to what I need.

I think it would be really nice if mdsh could also support a code block format like this:

```shellsession $ echo hello; echo there hello there ```

Instead of having to write: `$ echo hello` as shellsession ```shellsession hello ```

Particularly since the as ... will be rendered in the README, right? which is really not desirable.

That's an interesting idea, I wouldn't be against it if support for it was added.

One limitation is that it could only support blocks with a single command, as it's not possible to distinguish output that emits $ ..., but I think that's reasonable.

@juhp, I believe this issue was closed in https://github.com/zimbatm/mdsh/pull/59
