[PATCH v2 0/6] fix behaviors of git-push --porcelain

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

When executing git-push(1) with the "--porcelain" flag, then we will print updated references in a machine-readable format that looks like this:

    To destination
    =   refs/heads/noop:refs/heads/noop [up to date]
    !   refs/heads/rejected:refs/heads/rejected [rejected] (atomic push
    failed)
    !   refs/heads/noff:refs/heads/(off (non-fast-forward)
    Done

The final "Done" stanza was introduced via 77555854be (git-push: make git push --porcelain print "Done", 2010-02-26), with the following behaviors:

 - Show a "Done" porcelain message if there are no errors.
 - Fail to update a ref in a --dry-run does not count as an error.
 - Actual rejections in non --dry-run pushes do count as errors.
 - Return a non-zero exit code if there are errors.

This patch series try to fix the broken behaviors introduced in commit 7dcbeaa0df (send-pack: fix inconsistent porcelain output, 2020-04-17).
