[PATCH 0/7 v3] push.default upcomming change

I think I've applied all feedback I've received.

Additionnally, I've split the "start warning" patch in a documentation patch, that is meant to be applied now, and the warning patch itself, which is meant to be applied after the first released version introducing 'simple': we don't want to advertize 'simple' too loudly until the option starts being deployed.

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

Matthieu Moy (6):
  Documentation: explain push.default option a bit more
  Undocument deprecated alias 'push.default=tracking'
  t5528-push-default.sh: add helper functions
  push: introduce new push.default mode "simple"
  push: document the future default change for push.default (matching
    -> simple)
  push: start warning upcoming default change for push.default
