Ups, I forgot to tell you that you can change the default behavior
with push.default config.
push.default::
Defines the action git push should take if no refspec is given
on the command line, no refspec is configured in the remote, and
no refspec is implied by any of the options given on the command
line. Possible values are:
+
* `nothing` - do not push anything.
* `matching` - push all matching branches.
All branches having the same name in both ends are considered to be
matching. This is the default.
* `tracking` - push the current branch to its upstream branch.
* `current` - push the current branch to a branch of the same name.
