title: "git config --global credential.helper cache" not caching under win7+cygwin
body: <p>I'm using git on a win7 machine with cygwin installed (git version 1.7.9, not using cygwin bash but with cygwin/bin in the windows PATH variable and using the normal windows command shell) and in order to not have to type my credentials every other git command, I figured I'd use the credential helper,</p>
  
  <pre><code>git config --global credential.helper cache
  </code></pre>
  
  <p>however, after issuing this command and doing a git fetch from my git: repository, which prompts me for my password, any subsequent command that requires credentials still asks me for my password instead of using the cached values through the credential helper.</p>
  
  <p>Would anyone know how to make cygwin's git in windows 7 properly cache credentials? (All questions I could find on SO about this were for msys setups).</p>
