The 100% is to allow centering of stuff on the page. The table is a grouping mechanism to protect internal stuff from external centering operations.

The special{t4ht= is superior to \HCode{ because it can prevent <p>s from entering before <NOBR>.

The hbox is for avoiding the start of a new paragraph, if in vmode.
