      tmpl = File.read File.join Dir.pwd, "_includes", @text
      site = context.registers[:site]

    end
  end
end
Liquid::Template.register_tag('markdown', Jekyll::MarkdownTag)

was trying to include a markdown file that was not a post. and this does it perfectly.

Something weird seems to happen to the markdown with this plugin. For example, when using fenced code blocks, the newlines seem to disappear. I've also added support for MathJax to my installation, and the backslashes get removed. Explicit inclusion along the lines of

{% capture my-include %}{% include test.md %}{% endcapture %}
{{ my-include | markdownify }}

Doesn't have these problems. Any ideas how to work around these while still using the plugin?
