[PATCH] Fix error caused by missing parameter name

[Kian Kasad <kian@kasad.com>]

This fixes an error which was introduced by
2f50b47c72cbc4270bbd12ae7f520486d5f42736. Git added a new argument to
config_fn_t, and it was added to gitconfig_config(), but not named. This
causes compile warnings/errors. This commit fixes that by naming the new
parameter.
