title: git clone can't resolve proxy
body: <p>When I try to clone from git</p>
  
  <pre><code>git clone "http://github.com/symfony/symfony.git" "d:/www/a/vendor/symfony"
  </code></pre>
  
  <p>I get an error</p>
  
  <pre class="lang-none prettyprint-override"><code>Cloning into 'd:/www/a/vendor/symfony'...
  error: Couldn't resolve proxy '(null)' while accessing http://github.com/symfony/symfony.git/info/refs
  fatal: HTTP request failed
  </code></pre>
  
  <p>I'm connected directly to the internet (without proxy). I tried to turn off firewall and didn't help. I'm on windows and just installed Git-1.7.10-preview20120409.exe from <a href="http://code.google.com/p/msysgit/downloads/list" rel="noreferrer">http://code.google.com/p/msysgit/downloads/list</a> . Previously I had 1.7.8 and this command worked. I also reinstalled TortoiseGit but I think it doesn't matter.</p>
  
  <p>My <code>C:\Documents and Settings\xxx\.gitconfig</code> file is</p>
  
  <pre><code>[http]
      proxy = 
  [user]
      name = xxxx
      email = xxx@example.com
  </code></pre>
