Dear diary, on Sun, May 22, 2005 at 09:11:06AM CEST, I got a letter where Zack Brown <zbrown@tumblerings.org> told me that...

Well, and what if the commit has multiple parents? Or - even much more interestingly - multiple children?

If we keep applying the first parent rule, we could just traverse the graph from heads/master to HEAD following this rule, and then just take a step back to where we came from for cg-seek +. It wouldn't be exactly cheap, but it'd probably work.

Patch welcomed. ;-)
