djot-0.1.0.0: test/raw.test

Raw inline content:

```
`<a>`{=html}
.
<p><a></p>
```

Raw block-level content:

````
``` =html
<table>
```
.
<table>
````

You can't mix regular attributes and raw syntax:

````
`<b>foo</b>`{=html #id}
```
.
<p><code>&lt;b&gt;foo&lt;/b&gt;</code>{=html #id}
<code></code></p>
````

Attributes attached to raw content will just be ignored:

````
{.foo}
``` =html
<table>
```
.
<table>
````
