You jinxed it. ;)
It seems to cause problems. man.1 (attached) renders worse in the
current trunk than in Emacs 23.3. The woman-log buffer has many entries
that do not appear in 23.3:

**  Escape ignored: \- -> -
    [many times]
**  Escape ignored: \f -> f
    [many times]
**  ..  request ignored!
    [several times]
**  Numeric/register argument error: w'man 'u

An example of a section that renders worse is

   The following conventions apply  to the SYNOPSIS section and
   can be used as a guide in other sections.

   fBbold textfR@T{
   type exactly as shown.
   T}

In 23.3, "bold text" is correctly rendered in bold.

Also the spaces are missing between "man" and the arguments in the
following section:
   
   EXAMPLES
   
       man ls
           Display the manual page for the item (program) ls.
