[RFC/PATCH 0/3] push.default upcomming change

So, here's my first re-roll of Peff's patch. I've included the warning change in the same patch serie because topics are related and to avoid conflicts.

Compared to Peff's version, I've added testcases, but the 'simple' mode still lacks doc (I will do soon).

Clemens Buchacher (1):
  t5570: use explicit push refspec

Matthieu Moy (2):
  push: introduce new push.default mode "simple"
  push: start warning upcoming default change for push.default
