Everything in this patch was as expected (the most important of
which is where the data is kept, which is in the new structure
hook_config_cache_entry that was introduced in the previous step for
use case like this), except for the above bit.

I wonder if this already interacts well enough with "-z", or a minor
tweak would make it better?  Wouldn't a machine consumer expect that
friendly name and cope be given as two separate and easily parseable
fields in the same record?
