The syntaxhighlighter library strips blank lines at the start of code block it is trying to highlight. In addition to just being wrong, this means that line numbers on the source page will not line up with the real files. Work around this by providing the library with fake objects that ignore the attempt to strip these lines. This uses a fake string and a fake element to hold it. This is an ugly workaround, but allows us to continue using the syntax highlighter via npm.
Rather than padding empty lines with single spaces, we can use CSS to ensure correct alignment. This avoids copy/pasting code including invented spaces on empty lines.
