title: git-crypt update file thats been encrypted
body: <p>Ive a <code>.env</code> file, and a number of others encrypted with git-crypt.</p>
  <p><code>git-crypt</code> lock asks to clean working directory. Appending <code>--force</code> removes all changes to .env and just gives me the original file</p>
  <p>I'm adding new values into the <code>.env</code> file and want to re-encrypt the file anew, then check it in to git.</p>
