Garland heading patch needs review for D7

An important accessibility patch needs your help: Garland: Use appropriate header-tags following the W3C.

Please take a look and review this page. @mgifford, @JeffBurnz and many others have contributed.

It's simple to review this one: just start with Drupal 7 head and apply the patch (direct link below).

No other special data or setup is needed to test it. Just make sure that Garland gives an H1 for the site homepage title and an H1 for the content page title on other pages. There should always be 1 and only 1 H1. And make sure Garland's visual appearance is un-altered. I believe it's ready for RTBC so it can make the cut for Drupal 7.

Here is the comment with the patch:
