In the short term, you should probably try to run pandoc with the same 
version and options as CRAN.  Kurt, can you say what these are?  If you 
(Dirk) know pandoc options that emulate Github, it would probably make 
sense for CRAN to use those.

In the longer term, the plan is to include our own parser and renderer.  
At that point this would be easy.
