But that's the core of this article, too; since then it's normalized to store the plain text source code in git and share it, but it mentions a code and formatting agnostic storage format, where it's down to people's editors (and diff tools, etc) to render the code. It's not actually unusual, since things like images are also unreadable if you look at their source code, but tools like Github will render them in a human digestable format.
