title: Git pull/push history: Does Git save information who did a pull or push operation?
body: <p>If user A pulls in changes from master in a branch B and this is possible without a merge (no conflicts), is there a possibility to see who did this pull in Git history (or possibly other Git metadata)?
  I am assuming that the pull is pushed to the corresponding branch on a central Git repository. Is there a "push" history in Git?</p>
