Re: [PATCH 1/4] config: factor out config file stack management

The "do_config_from" means "parse from whatever is in 'top'". Later in
the series its type changes from config_file to struct config.

Yuck.  It would be nice to have it as struct config_src or
something. "struct config" sounds as if it represents the entire
configuration state and you can ask it to add new ones or enumerate
all known configuration variables, etc.
