CVS revision 1.4 of test case t040103-ident-03-c.xht

I've been looking at this test that was recently much enhanced to test valid
and invalid class and ID selectors more thoroughly and fix issues with the
earlier revisions, but I believe that there is still a problem with test
case 4.  This is the case of the selector that is:

#-1ident, .four { color:red }

The lexical scanners in the CSS2.1 (19 July 2007) and CSS3's Selectors (15
December 2005) specifications both agree that this selector is valid.  This
is because both of them define names the same way:

name   {nmchar}+
nmchar [_a-z0-9-]|{nonascii}|{escape}

%%

"#"{name}   { return HASH;}


Is this an incorrect test case or are the specifications themselves not
describing the intended scanner?  I'm not particularly bothered either way,
but the inconsistency needs to be resolved.

Browser behaviour is inconsistent for this entire test, too:

Opera 9.22 reports cases 1, 2, 5 and 6 as failures;
Firefox 2.0.0.1 reports no failures;
Safari 3.0.2 (522.13.1) reports case 4 as a failure;
IE 7.0 (5730.11) reports cases 3 and 4 as failures;

I agree with Safari - that's what our browser does too (which it would as I
wrote the CSS parser).  The patch below would fix the test to match the
spec, and making this patch reverses the results for each browser
(obviously).  All I've done is switch the red and green around.

If the test case is deemed incorrect, then there are a couple of others that
exhibit the same problem: t040103-ident-08-c.xht (case 2);
t0509-id-sel-syntax-01-f.xht
