title: Git log rebases
body: <p>I know that GIT rebases will rewrite the history -- i.e. the commit ids will change. However, Is there any way to trace when a branch was rebased and from which branch?</p>
  
  <p>EDIT: I have a development branch 'A' and a topic branch 'B'. 'A' is shared by the team. At some point, 'A' has been re-based with a mainstream branch. As a result of the re-base (and subsequent commits), when I updated the topic branch, I saw discrepancies. I am trying to find out the correct person to talk to to resolve the issues.</p>
