Funtoo Linux git-based Portage Tree Support

This commit makes genlop -r to work with Funtoo Linux git-based Portage tree.

I read that this is a long-term plan for Gentoo to support git-based Portage trees as well, so this commit might apply for Gentoo as well in the future.


Please let me know if I need to fill a request on bugs.gentoo.org for this feature...

Thanks!
