Subject: [PATCH v5 0/2] repo: add --keys and rename "keyvalue" to "lines"
Message-ID: <20260123164900.35092-1-lucasseikioshiro@gmail.com>

Hi!

There are two main changes in this v5:

- the "keyvalue" output format of git-repo-info and git-repo-structure were
  both renamed by "lines"
- the "default" output format was dropped

This way:

- `git repo info` accepts --format=lines and --format=nul
- `git repo info --keys` accepts --format=lines and --format=nul
- `git repo structure` accepts --format=table, --format=lines and --format=nul

Lucas Seiki Oshiro (2):
  repo: rename "keyvalue" to "lines"
  repo: add new flag --keys to git-repo-info
