[PATCH 0/5] Add a flag to push atomically

This patch series adds a flag to git push to update the remote refs atomically.

It was part of a longer patch series[1]. This series applies on top of origin/mh/reflog-expire It can also be found at [2].

Change since picking the series up from Ronnie.
  * other anchor point (i.e. where the series applies)
  * more tests for this feature, specially testing failures
  * drop the patch to rename ref_transaction_* to transaction_*_ref
  * slight rewording of the additional documentation
