LibMarkdown: Prevent a crash when rendering code blocks to console

Browse source 
When parsing a code block not in a section (in a file without a
heading), the parser would initialize the code block with an
uninitialized (invalid) value for current_section. Accessing this value
would later cause a segmentation fault in render_to_terminal.
