Hello,

While working on adding my package to Non-GNU ELPA, I noticed that the 
`make build/loopy` process collapsed the fenced code blocks in the file 
"CHANGELOG.md" into 1 line in the HTML output.

I have attached the Markdown file "CHANGELOG.md" and the outputted file 
"loopy.html". The squashed code blocks can be seen towards the end of 
the HTML file when viewed in EWW and Chromium.

Thank you.
