Code blocks not working

[Joakim Löfgren]

I use the gnome-terminal in Ubuntu 14.04 and for me the code blocks are not visible.

I used the npm module for marked and marked-terminal, e.g. in app.js markdisp(data):

  var TerminalRenderer = require('marked-terminal');
  var marked = require('marked').setOptions({
    gfm: true,
    renderer: new TerminalRenderer()
  });

Then the code blocks are visible but not very pretty, although I bet that's an issue
with the default options for marked-terminal.
