Message-Id: <E1K6BSK-0003e6-Iu@lionel-hutz.w3.org>

Update of /sources/public/html5/spec
In directory hutz:/tmp/cvs-serv13212

Modified Files:
	Overview.html 
Log Message:
Remove U+000B LINE TABULATION (VT) from the list of characters treated like a space character in HTML, for consistency with CSS. This is incompatible with IE7, but apparently IE has all kinds of complications here and in any case IE8 doesn't treat U+000B as a space character. (whatwg r1738)
