Displays nothing when file contains no comments

[lambda]

Rocco displays nothing on the code side unless there is at least one comment. Now, you may ask, why are you using a literate programming tool and then adding no comments? In a multi-file project, there are sometimes files that are so simple they need no comments, and yet which you would like to be able to browse for reference purposes.

For an example of the problem, see Rocco's output for its own comment_styles.rb; it comes out empty.
