title: "set number" in .vimrc not working in Vim for iOS
body: <p>I added the following .vimrc file to the home directory of Vim for iOS on my iPad.</p>
  
  <pre><code>set showcmd
  set number
  set guifont=Courier:h24
  imap jk &lt;Esc&gt;
  </code></pre>
  
  <p>For some mysterious reason, all commands work fine except <code>set number</code>. Since manually typing <code>:set number</code> still works, it can't be that Vim for iOS doesn't support displaying line numbers. I have no clue why it behaves differently when I put it in .vimrc. Any ideas? </p>
