I have implemented parsing math inline of `$...$` and `$$...$$` and I followed mostly how parsing is done for emphasis delimiters, but I’m not really convinced this is the best way to do it. I would in fact expect `$...$` and `$$....$$` to work a bit like a string with quotes (but would just allow escape with `\$`).

But looking at pandoc for example, with the following [case](http://johnmacfarlane.net/babelmark2/?text=This+is+a+test+%24%24this+is+a+test%24):

```auto
This is a test $$this is a test$

```

it is generating this:

```auto
<p>This is a test <span class="math inline">\($this is a test\)</span></p>

```

Unlike delimiters, I would expect that a `$$` should match an ending `$$`

I’m not sure how Latex behaves with this. Is this the way it is usually handled?
