Support lists and stylings in more places for `rustc --explain`

Adds support for `*foo*`, stylings not immediately following whitespace e.g. ``(`Foo`)`` and lists starting with whitespace:

```md
* previously supported
```
```md
 * now also supported
 ```

These are fairly common in the existing error docs, some before/after examples:
