Jaehwang Jerry Jung 59a551feb2 Don't let emphasis span multiple paragraphs ...

Most markdown implementations do not allow emphasis to span multiple
paragraphs. For example, commonmark.js, Markdown.pl, pandoc, and
Python-Markdown compile the following markdown

```markdown
*asdf

asdf*
```

to

```html
<p>*asdf</p>
<p>asdf*</p>
```

Some implementations compile it to

```html
<p><em>asdf</em></p>
<p>asdf*</p>
```

See https://johnmacfarlane.net/babelmark2/?normalize=1&text=*asdf%0A%0Aasdf*

Adding "^$" to :syn-end makes the emphasis end at an empty line like the
second compiled HTML above. While not perfect, it prevents an unmatched
`*` from emphasizing the entirety of the following text.
