[GSoC PATCH 0/2] repo: add -z and objects.format

Hi!

This patchset adds two features to `git repo info`. They are unrelated, but I preferred to send them together to avoid merge conflicts and because they are small.

- The first patch adds the `-z` as an alias for `--format=null`, as
  requested in [1]

- The second patch adds `objects.format`, which retrieves the same value
  as `git rev-parse --show-object-format`
  
Thanks!
