Issues with codeblocks

[tonyknight]

This is a great extension and works really well. Just what I was looking for.

I did notice one issue that cause my codeblocks to be malformed. The [```python] needs to have a linebreak before it render properly. I was able to fix this with find/replace. Just add a linebreak before this tag, and it looks bueno...

Thanks, Tony

Yeah I found this too, some markdown renderers need there to be a newline prior to the codeblock.
