https://bugs.webkit.org/show_bug.cgi?id=28118

           Summary: JSON.stringify replacer returning undefined does not
                    omit object properties
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: http://lucassmith.name/pub/JSON-test-suite/test.html
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: lsmith at lucassmith.name


JSON.stringify({remove:"me"}, function (k,v) { return k === 'remove' ?
undefined : v; })  should return '{}', but returns '{"remove":null}'

Per the ECMA5 spec, undefined returned from a replacer should result in
omission from the resulting JSON string in the case of object properties, and
null in the case of array items.  Currently, null is used for both cases.
