Code block not rendered correctly in a bullet list

[robinzimmermann]

The following markdown does not render correctly:

==== BEGIN example markdown ====

1. Run the following commands to achieve extreme success:

   $ cd ..
   $ echo "extreme success!"
   $ cd doc
   

2. Now keep going.

==== END example markdown ====

In OmniMarkupPreviewer, the code block is all written in a single line. In GitHub, it is rendered correctly as three lines.
