I think I've fixed the problems. Please take a look and make sure
the changes are correct:

http://test.csswg.org/svn-view/approved/css2.1/src/text/text-transform-bicameral-004.xht?r1=1683&r2=1684
http://test.csswg.org/svn-view/approved/css2.1/src/text/text-transform-bicameral-004.xht?r1=1686&r2=1688
http://test.csswg.org/svn-view/approved/css2.1/src/text/text-transform-bicameral-008.xht?r1=1683&r2=1684
http://test.csswg.org/svn-view/approved/css2.1/src/text/text-transform-bicameral-008.xht?r1=1686&r2=1687
http://test.csswg.org/source/approved/css2.1/src/text/text-transform-bicameral-004.xht
http://test.csswg.org/source/approved/css2.1/src/text/text-transform-bicameral-008.xht

I've also improved the usability of all the tests in the series by turning
each pair into a block / inline-block. And improved the accuracy by applying
text-transform only to the test character, not to the control character.
These changes are revisions
   1681 (split source into diffable lines, add inline-block display)
   1682 (use <div> instead of <span> per pair)
   1683 (adopt proper control styling)
   1685 (fix error in 1683)
   1686 (add blue to better differentiate test from instructions)
