I.e. we actually *do* have a repo there, we just haven't bridged the gap
of "ignore most of its config" so we can use config_with_options()
there.

	 struct config_options {
	        unsigned int respect_includes : 1;
	+       unsigned int ignore_system : 1;
	+       unsigned int ignore_global : 1;
	        unsigned int ignore_repo : 1;
	+       unsigned int ignore_local : 1;
	        unsigned int ignore_worktree : 1;
	        unsigned int ignore_cmdline : 1;
	        unsigned int system_gently : 1;

That does look (I am not sure about _local bit, though) well
organized, but I suspect that it can be left for a follow-on
clean-up series, perhaps?

Makes sense, I did suggest something similar previously:

But I think that's a follow up series for sure.
