We discussed this elsewhere in the thread, but if we are just adding
information (and not omitting existing information or shuffling it
around), I would prefer for us to make the format extensible using flags
than to add a whole new format enum. We can't imagine what other
information users might want (maybe the remote ref name?), and it would
be nice to avoid bumping the 'porcelain version' unnecessarily.

I agree that this format is good enough as a starting point, though.

It's not new to v2, but I've mentioned my reservations on
--output-format on:

  https://lore.kernel.org/git/kl6ledo33ovx.fsf@chooglen-macbookpro.roam.corp.google.com/

I will be out of office all of next week. If, in the meantime, everyone
else decides that --output-format=porcelain is good enough, I'm happy to
accept the result.

Now that the earlier test also tests without --dry-run, shouldn't this
one too?
