It seems streange to me to have a function named show_object when it
does not show anything. Maybe name it null_travers_cb to make it clear
it's a callback and it does nothing?
Not a strong objection though, it's only a static function.

I didn't test, but it seems this does a full graph traversal before
starting the output. A very important property of "git log" is that it
starts showing revisions immediately, even when ran on a very long
history (it shows the first screen immediately and continues working in
the background while the first page is displayed in the pager).
Is it the case? If so, it should be changed. If not, perhaps explain why
in the commit message.
