title: Why pulling from another repository do not pull all files?
body: <p>I had made repo 2 and a branch named branchNew, but this branch needed to be the same as branchOld from repo 1, so a tried git pull &lt;repo 1&gt; &lt;branchOld&gt; --allow-unrelated-histories   but some files didn't came, I tried to pull again but git said that my branch is already up to date. What I can do to make the new branch (branchNew) like a copy from the old branch (branchOld.) ? I think that is because the master from this repo 2 didn't have this files neither, so I don't know maybe git is ignoring this files.</p>
  <p>I tried putting files with the same name as the files I wanted in the branchNew, but didn't work. I also tried git merge &lt;repo1&gt; &lt;branchOld&gt;, didn't work.</p>
