modified header element definition in HTML 5.1

Hi all,

In response to a bug  [1] I modified the definition of the <header> element
[2] in the 5.1 spec [3] to match the Footer element in terms of relating to
the most immediate ancestor.

old text:

The header element represents a group of introductory or navigational aids
>

New text:

The header element represents a header for its nearest ancestor sectioning
> content or sectioning root element. A header typically contains a group of
> introductory or navigational aids.
>
> When the nearest ancestor sectioning content or sectioning root element is
> the body element, then it applies to the whole page.
>

Please review at your leisure, feedback welcome and appreciated.
