[PATCH 1/2] show-ref.c: Add missing call to git_config()

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

At present, 'git show-ref' ignores any attempt to set config
variables (e.g. core.checkstat) from the command line using
the -c option to git. In order to enable such usage, add the
missing call to git_config() from cmd_show_ref().
