Automatic linking when syntax highlighting

[hadley]

Need to post process to:

1. Convert .md to .json ast using pandoc
2. Read json into R, then apply pkgdown highlighting to each code chunk
3. Convert back to .json

Note that goldmark does not preserve raw html (like pandoc does), so it would need to include a shortcode in the output, along the lines of https://anaulin.org/blog/hugo-raw-html-shortcode/

Re: goldmark not preserving raw HTML: This is the default, but not only behavior. I tried the example from the linked blog post and included the following in a plain .md post rendered by goldmark:

<p class="speshal-fancy-custom">
    This is <strong>raw HTML</strong>, inside Markdown.
</p>

And the output is rendered correctly:

I think the relevant bit there is the unsafe setting in the goldmark config in my config.toml:

unsafe
By default, Goldmark does not render raw HTMLs and potentially dangerous links. If you have lots of inline HTML and/or JavaScript, you may need to turn this on.

[markup]
  defaultMarkdownHandler = "goldmark"
  [markup.goldmark]
    [markup.goldmark.renderer]
      unsafe = true

That way you would have to insist on this configuration, but would get away without an extra shortcode, but this option is already mentioned in the README anyway?

@jemus42 to see the problem you have to indent the raw html by 4 spaces

    <p class="speshal-fancy-custom">
        This is <strong>raw HTML</strong>, inside Markdown.
    </p>

Currently a bit slow; will have to improve performance in downlit.
