I agree that that’s a mistake, but I disagree with your suggested change.

The gitconfig_config() function is passed as the first argument to the
git_config_from_file() function which is defined in git/config.c. That function
expects the first argument to be of type config_fn_t, which does have the
context argument. This is why it was added to gitconfig_config(). Therefore, the
proper solution is to just give that argument a name, as removing it completely
could cause further errors:

	static int gitconfig_config(const char *key, const char *value, const struct config_context *UNUSED, void *cb)

Git seems to use the name “UNUSED” which is why I have followed suit here.
