Yup.
/*
* The object count is always accumulated in the .count_right
* field for traversal that is not a left-right traversal,
* and cmd_rev_list() made sure that a .count request that
* wants to count non-commit objects, which is handled by
* the show_object() callback, does not ask for .left_right.

Overkill? I dunno.
