[RFC PATCH v2 09/13] walken: demonstrate reversing a revision walk list

Message-ID: <20190626235032.177551-10-emilyshaffer@google.com>
In-Reply-To: <20190626235032.177551-1-emilyshaffer@google.com>

The final installment in the tutorial about sorting revision walk outputs. This commit reverses the commit list, so that we see newer commits last (handy since we aren't using a pager).

It's important to note that rev->reverse needs to be set after add_head_to_pending() or before setup_revisions(). (This is mentioned in the accompanying tutorial.)
