git-push to multiple locations does not stop at the first failure

When pushing into multiple repositories with git push, via
multiple URL in .git/remotes/$shorthand or multiple url
variables in [remote "$shorthand"] section, we used to stop upon
the first failure.  Continue the operation and report the
failure at the end.
