push: change `simple` to accommodate triangular workflows
When remote.pushdefault or branch.<name>.pushremote is set to a remote that is different from where you usually fetch from (i.e. a triangular workflow), master@{u} != origin, and push.default is set to `upstream` or `simple` would fail with this error: $ git push fatal: You are pushing to remote 'origin', which is not the upstream of your current branch 'master', without telling me what to push to update which remote branch. The very name of "upstream" indicates that it is only suitable for use in central workflows; let us not even attempt to give it a new meaning in triangular workflows, and error out as before. However, the `simple` does not have to share this error. It is poised to be the default for Git 2.0, and we would like it to do something sensible in triangular workflows. Redefine "simple" as "safer upstream" for centralized workflow as before, but work as "current" for triangular workflow. We may want to make it "safer current", but that is a separate issue.
