title: Weird character zsh in emacs terminal
body: <p>When using the terminal in emacs (M-x term) under MacOS for some reason it always posts the characters 4m before every line in zsh and always prints 2 lines containing the user info such as</p>
  
  <pre><code>4m--(jesus@laptop:/dir)----
  4m--(jesus@laptop:/dir)----
  prompt&gt;
  </code></pre>
  
  <p>It's more of an annoyance than anything but I was just wondering if there's a way to fix this. I also seem to have issues in Zsh in Mac OS emacs terminal mode when a lot of output is written to it it seems to reduce it all to one line and constantly overwrite the same line (may be related as the 4m is possibly just a special character that emacs is treating differently which can affect formatting).</p>
  
  <p>If need be I can post my .zshrc and .emacs files.</p>
