Subject: [RFC PATCH 02/13] walken: add usage to enable -h

From: Emily Shaffer <[email-masked]>
Date: Thu, 6 Jun 2019 18:08:00 -0700

One requirement of the Git test suite is that all commands support '-h',
which is captured by parse_options(). In order to support this flag, add
a short usage text to walken.c and invoke parse_options().

With this change, we can now add cmd_walken to the builtins set and
expect tests to pass, so we'll do so - cmd_walken is now open for
business.
