title: Why does git's cherry picking with more than one commit fail?
body: <p>I try to merge two repos, yielding a flat (aka interleaved) history. I do this along the lines of <a href="https://stackoverflow.com/a/14839653/188108">https://stackoverflow.com/a/14839653/188108</a>, under "History rewrite:".</p>
  
  <p>The two branches to merge are in "master" and "src/master".  Then, I write:</p>
  
  <pre><code>$ git checkout --orphan new-master
  $ git cherry-pick 9d325d6d 3f4c52ba
  error: a cherry-pick or revert is already in progress
  hint: try "git cherry-pick (--continue | --quit | --abort)"
  fatal: cherry-pick failed
  $ git cherry-pick 9d325d6d &amp;&amp; git cherry-pick 3f4c52ba

  <p>So, why does the first cherry pick command fail, but the split command works?  I use git 1.9.1.</p>
