Different issues:
$('[value=""]') also works in 1.3, but not in 1.3.1.
$('[value=]') as in ticket #3933 works in 1.2.6, 1.3 and 1.3.1 in the
following test:
http://jquery.nodnod.net/cases/77
It's probably related to the [attribute!=anything] fix landed on
1.3.1:
http://groups.google.com/group/jquery-en/browse_thread/thread/d70d3f31b892dc1e/9111f5f8e230211e
$('input:not([value])') will return all elements which don't have the
'value' attribute or where it is empty.
