title: Git can't find .ssh
body: <p>Problem using msysgit on Windows; it can't find .ssh/id_rsa, even though it is present where it should be.</p>
  
  <p>I verified that's the problem with ssh -v git@github.com; that command works when and only when I use the -i option to explicitly point it at the correct id_rsa file but as far as I can tell, git itself doesn't have such an option; and I can't find anything either on Google or in the supplied documentation.</p>
  
  <p>The peculiar thing is, it worked fine last time I used git a few months ago, and I haven't changed anything since then that seems a likely cause.</p>
  
  <p>I've tried the following, all to no effect:</p>
  
  <ul>
  <li><p>Generating new id_rsa</p></li>
  <li><p>Putting .ssh in current directory</p></li>
  <li><p>Putting .ssh in root directory</p></li>
  <li><p>Uninstalling msysgit and reinstalling the latest version</p></li>
  <li><p>Setting the HOME environment variable</p></li>
  <li><p>Installing TortoiseGit and trying that instead (didn't work at all)</p></li>
  </ul>
  
  <p>Any ideas what else to try?</p>
