html5/postmsg Overview.html,1.9,1.10

Update of /sources/public/html5/postmsg
In directory hutz:/tmp/cvs-serv6609

Modified Files:
	Overview.html 
Log Message:
Add a note to the 'fetch' algorithm about redirects. I'm sure it'll need tweaking later, since browsers ignore HTTP here for compatibility with deployed content. Also, tweak the W3C postmsg draft's boilerplate. (whatwg r4692)
