The problem seems to be in the filterANSIEscapes function, because when I remove where this function is called in the renderMarkdownToTerminal function I get the following output.

Funnily, the filterAINSIEscapes has the following comment over it:

// FIXME(jade): replace with TerminalCodeEater. wowie this is evil code.
