Local protocol-relative URL on oldIEs

Testing Isotope on IE7 locally.

I thought I’d be a smartypants ninja and use a protocol-relative URL for the HTML5 shiv as Google will serve both http and https, like so:

<!--[if lt IE 9]>
  <script src="//html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->

Turns out that IE7 did not load the shiv. Probably because the local URL for the site is C:\, which may be interpreted as file:///. Whatever the case, using the standard http:// got it working.
