The markdown files are stored in article/article.md so if they contain a
relative link to some screenshot.png, naturally that file is
article/screenshot.png. But because of the nginx rules where we visit
/writing/article, the relative link thinks that it points to
/writing/screenshot.png which doesn't exist. So this function turns all
relative links into absolute links starting from /writing.
