Revert "(GH-135) Do not convert description to code based on indentation"

This reverts commit ead3c750e1250922dfc0a2edc9ef3a0cae0cdbea.

There are issues with using the markdownsharp provided as source from the
release. I am not quite sure what is wrong but it is destroying any lines that
start with a space. Reverting now while I investigate.
