BREAKING CHANGE: `excludeTrailingPunctuationFromURLs` option was removed. This is now the default behavior
With this option enabled, this:
```md
> some text
> some other text
```
witll result in:
```html
<blockquote>
<p>some text</p>
</blockquote>
<blockquote>
<p>some other text</p>
</blockquote>
```
This is the default behavior of GFM.
