having problems with building the manpages

hi,

the man branch of git.git contains the following lines in git-diff.1:

EXAMPLES
       Various ways to check your working tree

              $ git diff            (1)
              $ git diff --cached   (2)
              $ git diff HEAD       (3)

              1. changes in the working tree not yet staged for the next commit.
              2. changes between the index and your last commit; what you would be committing if you run "git
              commit" without "-a" option.
              3. changes in the working tree since your last commit; what you would be committing if you run
              "git commit -a"

when building the manpages myself i get the followings:

EXAMPLES
       Various ways to check your working tree

               $ git diff            \fB(1)\fR
               $ git diff --cached   \fB(2)\fR
               $ git diff HEAD       \fB(3)\fR
           .sp \fB1. \fRchanges in the working tree not yet staged for the next commit.

           .br \fB2. \fRchanges between the index and your last commit; what you would be committing if you run
           "git commit" without "-a" option.

           .br \fB3. \fRchanges in the working tree since your last commit; what you would be committing if you
           run "git commit -a"

           .br

what can be the problem?

i have asciidoc-8.2.2 and docbook-xml 4.2 installed. i'm building with ASCIIDOC8=YesPlease.

if i missed any required info, please mention :)

thanks,
