If you push a branch that tracks the "upstream" repo to your repository, then you can see the diff in github itself, too:

 git remote add mainRepo github_url
 git fetch mainRepo
 git branch main_repo_master mainRepo/master
 git push origin main_repo_master

Then see it online like this:

https://github.com/rdp/mplayer-svn/compare/master…main_repo_master
