[PATCH] Initial cogito support

Hi Brian,

Attached is a patch that adds support for the cogito version control
system.  This is the system that is beginning to get used by the Linux
Kernel development team.  More information can be found here:

http://kernel.org/git/

I may have fixes and patches in the coming weeks as I am sure something
will break between versions of cogito.

Thanks,

Brandon
