+git push::
+       Works like `git push <remote>`, where <remote> is the

+The default behavior of this command when no <refspec> is given can be

++
+For example, to default to pushing only the current branch to `origin`
+use `git config remote.origin.push HEAD`.  Any valid <refspec> (like

+`git push origin`.

 git push origin master::
