It's expected that Git commands support '-h' in order to provide a
consistent user experience (and this expectation is enforced by the
test suite). '-h' is captured by parse_options() by default; in order to
support this flag, we 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.
