ACTION-58: Fix the styles in UCR 2nd WD (does not work well in IE or Firefow)

There are some display problems with the UCR Working Draft version at:
http://www.w3.org/TR/2006/WD-rif-ucr-20060710/.

Issue: The problems below need to be corrected.

Details: On the UCR Document Issues page, there is a note saying

Note: corrections have been sent, but are not yet visible.

However, the listed format problems are still present on 14 August 2006:
1. 2nd snippet in 2.8 should be class=\"nowrap\" (see correct layout on Doc
issue page linked below)
2. all snippets in 2.10 should be class=\"nowrap\"
3. in Firefox, 3rd snippet in 2.10 extends beyond the blue border, and in
IE 6.0 the next paragraph is somehow displayed within the border (as if part
of the <pre>), causing the page to extend horizontally (see also 2.9)

Issues Editor notes an additional formatting problem in 3 places, where a
tinted text box contains a final sentence that should be outside the box in
the main body of the text:
Section 2.8, (first tinted text box)
Section 2.9
Section 2.10 (last tinted text box)
