- Break up the long sequence of pipes into smaller assign statements.
- Interleaving comments and code snippets.

Earlier, the text following a Markdown blockquote became part of the
block quote incorrectly; fixed that by replacing "<br />" with "\n".

Also:

- Added more comments explaining the logic for parsing Markdown in
  comments.
- Removed a relic piece of code as a result of refactoring in
  ed10648d.

Now those rules apply only on «class="mf2 reply"» elements.

"site..." doesn't work but "$.Site..." works.

So now no need to think if .Site needs to be used vs $.Site. Yay!

To support the Org _underline_ syntax.

Google Chrome gives warning that the prefetched fonts are not used in
few seconds after page load (not sure why..).

Using the simpler Org macro instead:

    #+macro: asciinema /[[https://asciinema.org/a/$1][Click here]] to see the animation on asciinema.org./

The browser rendered bold of Iosevka is too squished up together (it's
very noticeable in the 'm' character); example:
https://scripter.co/splitting-an-org-block-into-two/#code-snippet-1

Turns out there's not much noticeable difference if I let the browser
do the bold and/or italic rendering of most fonts.

So now these are *not* loaded:

- Iosevka bold (for Interrobang too)
- Iosevka italic (for Interrobang too)
- Linux Biolinum italic
- Source Sans Pro bold
- Source Sans Pro italic
- Libre Baskerville bold
