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

[Emily Shaffer <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.)
