title: Git says "nothing to commit, working tree clean" even after I've made local changes
body: <p>I made a lot of changes to an index.html file and when I went to push it to the remote repo it says</p>
  <blockquote>
  <p>On branch master, Your branch is up to date with 'origin/master'.nothing to commit, working tree clean</p>
  </blockquote>
  <p>Here is how it went down:</p>
  <p><em>Made changes to file</em></p>
  <p>then</p>
  <p><code>git status</code> returns</p>
  <blockquote>
  <p>On branch master - nothing to commit, working tree clean</p>
  </blockquote>
  <p>then <code>git add .</code></p>
  <p><code>git status</code> returns</p>
  <blockquote>
  <p>On branch master - nothing to commit, working tree clean</p>
  </blockquote>
  <p>then <code>git commit -m &quot;added bio&quot;</code></p>
  <p>then <code>git status</code> returns</p>
  <blockquote>
  <p>On branch master - nothing to commit, working tree clean</p>
  </blockquote>
  <p>then <code>git push origin master</code> returns</p>
  <blockquote>
  <p>Everything is up-to-date</p>
  </blockquote>
  <p>I even tried <code>git branch --set-upstream-to origin/master</code> and nothing. I'm certain I'm in the correct local repo and I'm certain I'm linked up to the correct remote repo because I've been pushing to that repo for a week with no problems. This issue came out of the blue.</p>
