If a git push without any refspecs is attempted, display a warning.
The current default behavior is to push all matching refspecs, which
may come as a surprise to new users, so the warning shows how
push.default can be configured and what the possible values are.
Traditionalists who wish to keep the current behaviour are also told
how to configure this once and never see the warning again.

should happen upon such a push by setting the configuration variable
receive.denyDeleteCurrent in the receiving repository.
+In a future release, the default of "git push" without further
+arguments may be changed. Currently, it will push all matching
+refspecs to the current remote. A configuration variable push.default
+has been introduced to select the default behaviour. To ease the
+transition, a big warning is issued if this is not configured and a
