PDF output doesn't include bold text in verbatim code

[moritz]

In verbatim block code, B<...> should create bold code. And the latex output has all the required commands for it, it just seems that the current monospace font doesn't support it (which was the reason for chosing the "bera" mono font in the first place).

So font needs to be chose that supports bold monospace.

Others on the net have bemoaned this issue.
