title: Getting 'fatal: empty ident name not allowed' when doing 'Git commit --amend'
body: <p>I am doing a <code>git commit --amend</code> and I get this error:</p>
  <blockquote>
  <p>fatal: empty ident name (for &lt;&gt;) not allowed</p>
  </blockquote>
  <p>I've found a bunch of stuff saying I need to set my <code>user.email</code> and <code>user.name</code>, but I have. This is the the result when I do a <code>git config --global --list</code>:</p>
  <blockquote>
  <p>core.exludesfile=/home/dzou/.gitignore<br />
  core.editor=vim<br />
  user.email=dzou@company.com<br />
  user.name=dzou</p>
  </blockquote>
  <p>What is going on here?</p>
