[PATCH 0/2] clean up push config callbacks

> But here you are adding to git_default_push_config, which is in another
> file.
> 
> I'm trying to figure out why git_default_push_config exists at all. The
> major difference from git_push_config is that the "default" variant will
> get loaded for _all_ commands, not just "push". So if it affected
> variables that were used by other commands, it would be needed. But all
> it sets is push_default, which seems to be specific to builtin/push.c.
> 
> So I suspect it can be removed entirely, and folded into
> git_config_push. But that's outside the scope of your patch.
